Students, when the nucleus of an atom
splits into two or more smaller nuclei,
it is called Nuclear Fission.
And this splitting action releases a very large amount of energy.
However, an atom that is split can also be combined together
in a reaction called Nuclear Fusion.
The chapter on Fission and Fusion is a bit tough.
So, we'll come back to it later.
For as you know, we always begin with the easier chapter first.
But bear in mind. It's the 12th Board this time. So, no chapter is easy.
Take out your notebooks. Put today's date and start writing carefully.
'8 - 8:30 - Talk to Ishita'
'You'll keep talking for the entire half an hour. What about me?'
'By the way, dad is going to be home late tonight.'
'Shall I come over then?'
'Oh. I hope he comes back on time. You should call him once.'
Post the last term, everybody's life has seen a lot of changes.
Our dear Kaushal sir teaches here now.
At the Guidance Institute of Excellence.
No doubt the students and the fees both are more here than Sunshine
and so is my salary.
These kids' lives too have changed.
Some equations have been newly formed.
And some others have gotten stronger.
In short, we all have undergone a Nuclear Transmutation.
As the number of neutrons and protons changed,
so did the identity of the elements.
What will happen as a result of this transmutation
can only be known at the end of the term.
Bro, Guidance may be bigger and better
but the real fun was on Sunshine's terrace.
Ishita on one side and me on the other.
The way we looked at each other love struck.
I still remember the feel, bro.
Hey, Nerdy. Hey, you tappy-mouth.
Tippy, tippy, tap.
Listen up, nerd.
Bro, my apologies and
-condo... condol... Yes, condolences. -Condolences.
Let me study.
What's wrong, bro?
It's alright. If one girl dumps you, another will come your way.
-Rajat, you know what? -What?
Every girl dates a nerd for sure once in her life.
You know why?
To eventually understand what she does not want.
Hey, you shorty. Don't run your mouth too much.
Dude, it wasn't the girl. It was I who broke up.
-Why so? -Why?
I used to score 97% before I got into the relationship.
-And then only 95% in my half-yearly. -Oh, no.
And you broke up for a mere 2%?
I didn't do it for the 2%. I did it to get ahead of two lakh students.
Do you know the cut-off for St. Stephens?
What was your 11th-grade finals score?
82%.
-42%. -And what about the 12th half-yearly?
71%.
-My apologies and condolences. -Get lost.
What was that, Mr. Pandey? I can hear you very well.
Kindly treat this as a classroom and not your roadside eatery.
-Sorry, sir. -Alright, then.
Let's start.
We're going to study Polymers today. It is important as it carries 15 marks.
Okay, let's begin. So, what's the name of the chapter?
Polymers.
I'm thinking of suing my brother.
He'll get convinced. Don't worry.
I've been screaming my throat out and saying that I want to do Journalism.
But no. With ten Venn diagrams, twenty excel sheets,
and two PowerPoint presentations, he is hell bent on convincing me
that journalism is not worth it.
-Is your brother a CA or a Lawyer? -He's a snake, a vile snake.
Blocking the path of my career like a fanged snake.
How on earth did you convince your dad?
He didn't need any convincing.
I simply said that I'm going to study Economics.
Honestly, life is so sorted for you guys.
Even Rajat's dad is supporting him.
Only my brother isn't budging.
Why don't you tell your brother to talk to Rajat's dad?
Thank you.
I'll deal with it myself.
Students, thousands of ethene molecules
make the polyethene polymer. What does it make?
-The nerd is right, you know. -Polyethene polymer. Right?
We won't get into any good college if we don't get good marks.
At such times when people break up, Ishita and I have patched up.
What if I'm unable to manage my studies?
You know what's your couple name?
I'll tell you.
A mess. For the past one and a half years,
your relationship has been a mess.
Now that you guys have patched up, you might as well just enjoy.
Don't mess it up again.
Mr. Pandey. What will you take to keep your mouth shut?
-I can hear you clearly. -Sorry, sir. My apologies.
Pronounce the word apology properly first.
Pay attention, everyone.
-What's taking them so long? -Who?
-Katrina Kaif. Ishita and Anusha, who else? -Buddy, just chill.
-Hi, boys. -Hi.
-Hello. What's up, girls? -Don't cling to me.
When are we meeting tomorrow?
My parents are leaving at 4 o'clock. So, let's meet from 4 to 6.
That's great. You guys can grab one room and we both can grab another.
To do combined studies.
You know what? You should think twice before you open your mouth to talk.
-You'll zip your mouth yourself. -I have a suggestion too.
If you had preached such wisdom to your family, they would've agreed for BJMC.
You wouldn't be preaching to me for the freedom of your freedom of speech.
Hey, Pandu, not funny.
It's good that you're pretty.
Sorry. Sorry, guys.
Are you coming or shall I go?
Hey, he was just kidding.
-Wait, I'm coming. -Bye, ladies.
-Bye. -See you after the break.
Damn it. Look at the mess you created now.
My parents agreed to a group study only because I said Anusha needed help.
-What if she doesn't turn up now? -Why are you so desperate anyway?
Well, the thing is...
-Actually... -What?
-You don't know the flavour of her lipstick? -Lower your voice.
No, I don't.
Nothing has happened since our patch up.
Group study is just a facade.
Bro, you really need to learn from me.
Park, theatre,
deserted roads, both of us get cosy even in the institute building, bro.
The other day, she was alone at home.
I went over to her place and cuddled cosily with her.
-Cuddle? What's that? -Seriously?
You don't know what a cuddle is? To hug lying on the bed is called a cuddle.
-Really? -Watch me.
First, lie down with your chest wide open as if you're the boss. Okay?
Then spread your arms like Shah Rukh Khan.
Now, come. Come into my arms.
Now, close your eyes and imagine
that her head is resting on your shoulder.
And just hold her tightly in your arms. Oh, my, my.
-What next? -Step 1, sweetly and lovingly,
just go on talking to her, on and on.
-What next? -Step 2.
Gently caress her soft and silky hair.
Even if they are a bit short. Never mind.
-She's your girl, after all. Step 3. -What next?
Momos. Sir, your momos.
You spoiled the whole moment, man.
-Sorry, sir. -Look at you shoving it right into us.
Please continue.
And listen.
Do wear some perfume and go. It makes it more exciting.
-Not to worry. -Hey, cuddle-master.
The way your partner left fuming, that was your last cuddle.
You're such a kid. Check this out.
She asked me if I was free. I said, I wasn't.
Look at the long voice note.
I didn't even bother to listen to it.
She got angry. So, I took her to the Japanese park.
We had Chinese food and did a French kiss.
Right then and there, I gave her a nice world tour, bro.
All our problems have only one solution, a cute selfie. Check it out.
Every matter gets sorted out, bro.
You guys are damn lucky.
Doing world tours right here.
We're still stuck where we were.
You bro is right here, dude. I'll get things ignited for you.
-For sure? -You're doubting me?
Have momos and just chill, buddy. I'll arrange a tour for you and Ishita.
-Have this. It's hot. -Oh, yes.
The clothes are still wet. They haven't dried well.
It's nice and sunny today.
-Turn it over and spread it out. -I've wrung it well, mom.
-Come on, let's go, Geeta. -Yes, I'm coming.
Are you wearing your dad's perfume?
Who all are coming for group study today?
I had told you, remember? Pandu, Anusha, Rajat.
I mean, obviously, I'll be there. And one more friend will be coming.
-We're going to study calculus and... -Hello, aunty.
Hello, my dear.
Here's your friend.
Pay attention to studies.
I'll test you after I'm back.
Your underwear has fallen.
So, how are you, my dear?
-I'm fine, aunty. He's fine. -Seeing you after long. How's your dad?
Tell me something. How much is sin square theta plus cos square theta?
Aunty, one.
One.
Superb.
-Learn from her. I know. -Mom, dad's honking.
-Okay, bye. -Bye, aunty.
-Geeta, we're getting late. Come fast. -I'm right here.
Awesome.
So, shall we go in?
'Actually, the other day, I could have come to your place.'
Princey.
Queeny.
Baby doll, thank you for coming for the group study.
So sweet of you.
I'm not here for you. I'm here for my friends.
-'Wow.' -Listen.
-'Tubelight.' -Pretty woman.
Sweet angel.
What is it?
Remember the photo I posted the other day? Me with the BMW.
With the caption, daddy's ride, my pride.
That wasn't my car actually.
It was just parked there. So, I posed with it.
Why are you telling me this?
-Rajat, look at him. -Sure, he's very handsome.
-'Oh. By the way, today, my parents aren't home.' -Hello.
-Anusha. -Pandu, just shut up, man.
-Anusha. -What is it?
I'm just keeping you informed so that in future,
you'll have some reason to humiliate me.
You're pissed off at me since yesterday for what I said.
So, now, by telling you this, I'm just making it even.
Are you here to study or just yap?
What an insufferable girl.
She's going on getting pissed.
'What about these two?'
-'We'll send them home early by 4:30.' -Stop this non-stop pinging.
We're here to study and not chit-chat.
All of you are insufferable.
Rajat, I also have some doubts.
I'll be in and out by 5:30. I promise.
Please open.
-For sure? -Yes. For sure.
Alright. Come on in.
If I keep sitting, I'll get cramps.
I'll go out and stretch a bit. Okay, guys?
Why are you announcing it?
Hilarious joke, girl. Hilarious.
-Take this pest also with you. -No, I'm fine now.
Get lost.
'Listen, take a 5-minute break and come out.'
Even I can't figure it out.
I'll just call my dad and be back.
'I've taken a break. Where are you?'
What happened? Why did you come running?
You're the one who texted.
I did.
-But didn't you text me first? -Not at all.
-I didn't text anyone. -Rajat.
What happened?
-You want to cuddle? -What?
How did you know?
Rajat, Pandu is your close friend.
And Anusha is mine.
And they both are very close to each other.
Yes, that they are.
So?
-You don't want to do it? -I want to.
-I want to do it. -Then shall we?
Everyone is out there.
You want to call them here?
Should I?
But Pandu didn't say so.
Sorry, so sorry. Yes, let's do it.
Step aside for a second.
Rajat, what are you doing?
-Ishita, come. -You want to lie down or sit?
We can sit.
Whatever the world may think of you,
for me, you're the cutest.
Thank you, Ishita.
Oh, God. Who is it this time?
Where were you?
What took you so long? Where were you so busy?
-Why have they parked inside? -Didn't you hear the doorbell?
-What's going on? -Just some discussion. Nothing much.
-Fine. Step aside and let us come in. -Alright.
Who knows what he was up to.
So, kids, this is your last year.
What are your plans after this?
Your plan?
Yes, I have a plan, uncle. I do.
My Plan A is to follow Plan B.
And
Plan B is still in the planning process. So...
It'll be done, uncle.
Rajat is so right about you.
-Never change yourself, son. -Thank you, uncle. Cheers.
-What about you? -Uncle, I'm going to do Journalism.
Only if her brother agrees.
-Shut up, Pandu. -What are your plans, Batri?
I'll be going to Mumbai, aunty, to study B.Com.
-You're going to Mumbai? -Yes.
Ishita also had the same plan earlier.
But now, she has betrayed me.
No, aunty. It's nothing like that.
There's just a slight change of plans. So now,
-I'll study Economics at DU. -That's great.
Her plan to change the plan was good.
Have you done any research?
Man, you guys almost got caught today.
Seriously.
Listen, Ishita, I need to call Varun.
So, you guys carry on.
-Bye. -Bye.
Who's Varun?
Someone special.
Oh.
He's sorted too.
Ishita, is everything alright?
Yes.
Are you sure?
Look, if I've done something wrong, you can tell me.
Rajat, I'm not in the mood for it now.
-Let's talk later. -Means something is definitely wrong.
I knew it.
Ishita, if I've made any mistake, then please tell me.
Did I do something wrong in the room?
-Rajat, you didn't do anything wrong. -If not, then you'd have told me.
-I'm sure something is wrong. -Rajat, stop it.
Just because we're together doesn't mean all my emotions depend on you.
Sorry.
I want to have some ice-cream. Let's go.
Are you coming or not?
Anusha, where are you going?
Anusha. Anusha.
What is wrong with you?
Where are you off to?
-Give me your phone. Your phone, now. -You want to take a selfie?
Here you go.
The other day I asked you if you were free. Do you know why?
I fought with my dad that day.
And he said that no matter what, he won't allow me to do BJMC.
-Why are you digging the past? -Hold on.
Listen. Pandu, I called you but you didn't pick up.
I'm very anxious about my career.
My brother is simply refusing to budge.
-Anusha, what's the point? -Had you spent even 10 seconds,
you would have understood what I was feeling.
-You're overreacting now. -A cute selfie can't solve all problems.
Sometimes you need to pay heed to the other person too.
-People are staring at us. -One more thing.
Let's not meet too often.
But what the hell have I done?
With this excel sheet formula,
it's easier to memorise the periodic table, you see.
Kaushal, you're very hard working.
You'll manage it well.
Just don't stress yourself out too much.
-No, no. There's no stress. -Kaushal sir.
Yes, please come in. I'll talk to you later. Okay.
Hello, sir.
-Hello. -Hello, sir.
Hello, son. Yes, tell me, sir.
Sir, because of your fame,
I got him enrolled in such an expensive institute.
But, sir, looking at his half-yearly marks,
we're quite worried.
I see. How much did you get, son?
Sir, well, 52%.
-That's certainly less. -Sir, actually, my doubts
aren't getting solved in the class. There are so many students, so...
I mean, the class ends by the time I ask my doubts. Which is why.
Well, you needn't worry so much, sir.
We still have five months in hand.
Raghav and I will work it out. Right, Raghav?
-Yes? And I guarantee you, sir. -Absolutely, sir.
Your son will improve a lot by then.
So, rest assured. You have my word. Alright?
-Let's start from tomorrow morning. -Sure, sir.
-I'll wait for you. -Sir, I'm in the evening batch.
Oh. Well...
There's a Raghav in the morning batch too. Don't you know him?
No, sir.
I'll introduce you to him. He's also a hard working boy.
So, see me in the evening then.
And my number is available at the reception.
-You have it? -Yes, I have it, sir.
For any doubt, feel free to call me anytime.
Don't worry, sir. He'll score very good marks.
I promise you.
Very well, sir. Thank you.
-You are welcome. -Thank you, sir.
Ishita, ice-cream in winter?
-Ishita... -Don't.
This is the first time I've seen you silent for five minutes.
You must have felt good.
Ishita, at least tell me now.
I mean, it's okay if you don't want to. No rush.
Shall I get you one more ice-cream?
Rajat, you're too sweet.
You know, when I was a child
and my parents used to be away at work,
I used to feel lonely in their absence.
And after they would come back home,
I would feel lonely because of their fights.
And you know how Batri's dad is.
Very well.
That is why since the 8th grade, Batri and I
started bonding with each other over our family traumas.
We used to make plans that after our 12th grade,
we would go away to another city or so.
But
after my mom passed away,
I didn't give it a thought at all.
Dad's dependency seemed more important than my independence.
But today, when Batri mentioned it...
Ishita, you're the best.
The best daughter, best person,
and a so-so girlfriend too.
Your decision to not leave your dad and me is just perfect.
Wow.
My dad, I get it, but when did you come into the picture?
-Come on. -Let's say, I leave someday.
What then?
Delhi will be very sad.
And this Delhi guy too.
-Come on, copy me. -What?
Turn your chair around.
Alright.
Settled?
Tring. Tring.
Tring. Tring. Your phone's ringing.
-Hello. Hi. -Hi.
How was your day today?
Very bad.
I had plans to cuddle but it never happened.
I see. So, you've made a new girlfriend?
Well, what choice did I have? The old one dumped me and went away.
-You tell me. What's up with you? -Nothing much.
I'm at the market.
But there's this creepy guy here who is going on staring at me.
And he just turned around.
He's cute though.
Oh, really?
One second.
Hello. Yes, dad.
Oh, is it? Fine. Okay, bye.
Okay, listen. My dad just called.
He said he's going to be late. So, I'm going home to cuddle with my boyfriend.
Alright? Okay, bye.
-Ishita. -Bye.
Wait up. I'm coming.
So, students, like I said,
changes are inevitable in everybody's life as a result of transmutation.
Pandu, I called you, but you didn't pick up.
I'm very anxious about my career.
I don't know what to do. Please answer my call.
And remember that Chemistry is the study of change.
Which talks about three things.
Anusha. Come on, dinner is ready. We're waiting for you.
Come quickly.
Transformation.
Decay.
And growth.
Students, remember I mentioned earlier about nuclear transmutation?
Somewhere the protons are increasing and somewhere they're decreasing.
And as you know, this will lead to a change in equations
as well as the behaviour of atoms.
That's a nice perfume you're wearing.
