Entropy of Plasma

Equation of state for quark-gluon plasma is

p=(127/6) (stephan-boltzmann const/ speed of light) T^4

internal energy is

U=3pV = (127/2)(stephan-boltzmann const/ speed of light)(T^4)V

So how does one get an expression for entropy? or if anyone knows the expression what is it? (I may be able to work backwards)

Cheers

Hey! Welcome to PF.

Where did you found these expressions?. I didn't know it exists a equation of state for a plasma!. The question is: how can one measure the propierties in a plasma for built up any equations?. I don't understand some people...


Well, to answer your question:

1st principle: [tex] dU=TdS-PdV[/tex]


what happens if you make [tex] S=\int{\frac{dU}{T}+\frac{PdV}{T}}[/tex]?

Spannie, could please give some info on how you acquired these formula's you are using in order to describe this quark-gluon plasma.

Shouldn't you be using the SAHA-equation ??? Just a thought...

regards
marlon
