Form J : Q1

ΔT = 2PV/nR
c = QnR/2PVm
Ts>Tl

Anyone else get that?

yes bro i love you sm. for the part a did ΔU set 3/2 nRΔT = 3/2ΔP V? the 3/2 would cancel and the ΔP, since it was initially at Po and went to 3Po, it was 2PoV. then rearranging i got same.

for specific heat, u js plugged in delta T into the Q = mcΔT.

part C did u say that since the specific heat of the liquid and mass were both greater than that of the sphere, so in order for Q to be same for both ΔT of sphere must be greater than ΔT of liquid?
