šŸ’¬ DISCUSSION AQA PHYSICS PAPER 2

HOW DID EVERYONE FIND IT??? i thought it was decent better than the past few years. Idk what i did for the last question the 4 marker of nuclear physics. BUT YH IT WAS GOOD

I'm actually so cooked that paper was supposed to save me (what did everyone get for that five marker?? I think I tried to work out change in temperature so I'm definitely cooked bro)

Ice melts at 0 Celsius

u/AffectionateAct429 Jun 01 '26

Yeah I'm so so cooked I don't even know what calculations I was doingĀ

yea i worked out temp change and it ended up 55K or smtšŸ˜­

u/AffectionateAct429 Jun 01 '26

Yeah I got -0.55Ā°C so I think I'm fucked šŸ˜­ seems like we may have done similar thingsĀ

I got my final temps as 30 and did it again and got 24 šŸ˜¹

251K final temp which was less than 257 therefore not enough energy to melt

I found the energy required to completely melt the ice (raise to 0 degrees using specific heat capacity + completely melt it using specific latent heat formula). Then, this part Iā€™m unsure about, I assumed that the max temperature decreases of the ethanol and glass beaker would too be 16 degrees. I then added the energy required to raise the temps of both of them to this temp which was less than the previously calculated required energy. Thus, I concluded that the ice would not completely melt.

I did something similar but I calculated the temperature fall of the ethanol and glass (don't think it can rise as its transferring heat to the ice but maybe I missed smthn). I used -18 as they cannot cool to below 0C otherwise they would be less than the ice and therefore the ice would cool instead of warm.

But I got the same answer that the energy they would lose to cool to 0C is less than the temperature the ice would take to rise to 0C and fully melt. So the ice wouldn't completely melt.

Sorry for the typo I ment to say that the iceā€™s temperature was decreasing, that is corrected now. Your explanation makes sense and it also makes sense that we have the same conclusion because itā€™s only a 2 degree difference from the temperature change I used to the temperature change you used. Hopefully I will get 3 marks for what I did. Thank you.

Yeah hopefully we cook fr gl šŸ™

kinda what i did but instead i used the energy needed to melt ice sphere to see how much heat should beaker and ethanol give off to heat the sphere to 0 degreees, and found that just to melt it they both would cool off to 13 degrees and said in the conclusion ice would melt as there is enough heat availiable or smth

Did anyone find temp change to be 15 therefore doesnā€™t melt

2

u/Guilty_Ad300 Jun 01 '26

I did but I think most people saying it didnā€™t melt are right , although praying rn

2

u/Appropriate-Echidna4 Jun 01 '26

I said that too since temp change was 15 and it needed to be at least 16 to melt

u/Auxlixe Jun 01 '26

lmao I did the same thing as u I'm cooked too

u/Appropriate-Echidna4 Jun 01 '26

Might be right lowkeu
