**drwls**, Friday, April 30, 2010 at 7:43am(a) During the expansion, the product

P*V^(5/3) remains constant. You know the ratio V2/V1. Use the adiabatic relationship to calculate P2/P1.

P2/P1 = (V1/V2)^(5/3)

= (6/7)^(5/3) = 0.773

(2) The work done is the integral of P dV from V1 to V2. Express P as a function of V and integrate

P(V) dV = [P1*V1^(5/3)]*/V^5/3)]dV
