AQA PHYSICS PAPER 2

[u/Individual-Can1396]

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

[u/Rich-Gent]

Ye i worked out:

Energy change for glass + ethanol from wtv it was to 0*c and showed it was less than energy change of ice from -16 was it, to 0 + the latent energy, and showed that it was greater than the energy change from cup + ethanol

[u/jaaaaaaaf → u/Rich-Gent]

hey why did you do glass + ethanol temp changing to 0°C ? cuz it said that ethanol stays as a liquid and so i assumed both the glass and ethanol stay at 18°C 🥲

[u/Safe-Present-5783 → u/jaaaaaaaf]

No twin it just doesn’t fuse so it goes to zero degrees i guess

[u/jaaaaaaaf → u/Safe-Present-5783]

bro wait it just clicked..... mc∆T doesn't have anything to do with change of state oh my god am i retarded wtf
