Homework Statement
Gas has a heat capacity of (Cv = (3/2)nR), intial temp of To, pressure Po and volume Vo.
Process a to b is a quasistatic isobaric expansion to twice the intial volume
Find
a) work done,
b) heat transfer,
c) change in internal energy,
d) change in enthalpy
e) change in entropy
In terms of n(moles), R, T0
Homework Equations
W = -P(delta)V
(delta)U = Q + W = (f/2)nR(delta)T
PV = nrT
H = U + PV
The Attempt at a Solution
Now this is what I've come up with but I am unsure about enthalpy and entropy (this mostly), they seem ok but look wrong. I don't have any answer or similar questions to check it againt first and only isobaric cycle. Looking on the net I've found mostly constant U, while V changes which isn't helpful.
Attached is my attemp if any1 can shine any light on the last two points or anything else
Thanks Trent
