## Homework Statement

By applying the first law to a quasi static process, show that the entropy can be expressed as

S = (16σ/3c) VT

^{3}

## Homework Equations

U = 4(σ/c) VT

^{4}

PV = 1/3 U[/B]

## The Attempt at a Solution

I know I should be using

dS = dQ/T but it's unclear to me how to use this unless I took the integral for arbitrary volumes, I couldn't find any examples in my text or online to try and get it myself [/B]
