Thing is, heat isn't the same as temperature, it's simply a form of energy (thermal energy). When the substance inside the test tube absorbs heat in the chemical reaction, the thermal energy is converted into chemical potential energy that is "stored" inside the molecular bonds. This is because...

The Crucible

Aeughhh I swear they're overcomplicating things, it's all nonsense and you could probably get away with random, seemingly philosophical statements using the keywords of the rubric :pold: But luckily they omitted the related text for us, so that's a relief :angel:

Actually same, I think it's because knowing the theory isn't enough for chem, you need to know how to approach questions effectively

Ohhhh ok I think I get it now, thanks 👍 I think I was assuming that each bed was also an option too

I thought it was yr 10? But the way you explain it suggests that you're really confident with it, idk though it's your call

Wow... why aren't you taking chem next year?

dangg you all are on another level

How is this place already almost as active as the 2025 chat :eek2:

I'm new to perms and combs and this is already confusing. Apparently the answer's 4^4 but I don't get why you don't need to account for double-ups? Explanations appreciated 🙏

I don't know, if your school doesn't use/provide it then it might not be worth it, but maybe check with your teacher? Just Cambridge is probably sufficient too

Cambridge is good, but Fitz also has some great questions. The chapter reviews are also short and sweet, which helps

We actually started with Combinatorics because we did Proof by Induction in Yr 11, it's all a bit messed up

Really? Our school still forces us to do the 2U exams even if we do 4U, just in case we drop

nope

Don't worry, it's really hard to lock in right now because of the pressure, especially since you want to do so well. I barely did anything either this weekend because there's so much to consider, but sometimes you just need to procrastinate. The fact that you dare to set 99.6+ as your goal says...

What are they gonna give us then? Persuasive?? INFORMATIVE??!

Hmm okay I guess it's time to GRIND :evilfire:

Yeah I heard about maths adv... I'm pretty much cooked for Eng Adv already. How are they going to make Biology hard?

no idea
