Hi, I have the following problem:

The pressure,p, and volume,V, of a gas undergoing a polytropic process are related by the equation

p1V1^n=p2V2^n

wherenis the polytropic index.

If (p1V1)/T1 = (p2V2)/T2

determine an expression forp1, in terms ofp2,T1,T2 andn.

(1 and 2 should be lower case) formatting didn't quite work!...
