Well, we are given:
So, to say:
Therefore:
Now, using the equivalency before:
So:
We know that:
So therefore:
Any help would be really apreciated with the question
the pressure , p, and volume, v, of a gas undegoing a polytropic process are related by the equation -
where n is the polytropic index
if p1V1/T1 = p2V2/T2
Determine an expression for p1 in terms of p2,t1,t2 and n.
