**drwls**, Thursday, April 9, 2009 at 5:47amIn the isothermal case, P*V = constant = P1 V1.

The work done is Integral P dV

= Integral (P1 V1)dV/V

= P1 V1 ln(V2/V1)

In the adiabatic case,

P*V^(5/3) = constant

(for monatomic gases)

The work is once again Integral P dV, but you get a different answer.

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