Why entropy is an abstrat variable more then internal energy and enthalpy ?
我是假设 ideal gas
△U = f(T) only
△H = f(T) only
△s = dQ / T = d(△U + W) / T = f(P,V,T)
不知道这样写O不OK?
还是有更好的答案吗!?
感谢!!

2F：→ theknight:感觉不太好 题目没指IDEAL GAS 03/31 13:08
3F：→ theknight:Qr =/= Q 大概是这样 03/31 13:10
4F：→ theknight: ? 03/31 13:10
