## Homework Statement

Gas has a heat capacity of (C

_{v}= (3/2)nR), intial temp of T

_{o}, pressure P

_{o}and volume V

_{o}.

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, T

_{0}

## 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 ive come up with but im unsure about enthalpy and entropy (this mostly), they seem ok but look wrong. I dont have any answer or similar questions to check it againt first and only isobaric cycle. Looking on the net ive found mostly constant U, while V changes which isnt helpful.

Attached is my attemp if any1 can shine any light on the last two points or anything else

Thanks Trent
