I have a question relating to a polytropic process. The question consists of two parts.

It says that the pressure (p) and the volume (v) of a gas undergoing a polytropic process are related by the equation:

p1V1^n = p2V2^n (where P1, P2 etc are individual variables as i don't know how to put sub text into the question)

the question then says...where n is the polytropic index.

IF

p1V1/T1 = p2V2/T2

determine an expression for p!, in terms of p2,T1,T2 and n

I have had a look on the net for help in answering the question but not luck so far.
