**drwls**, Thursday, November 18, 2010 at 6:05pmP V^g = constant during an adiabatic expansion.

You need to know the value of the Cp/Cv specific heat ratio, g (usually called gamma) to compute the P dV integral (work done).

Just calling it an "ideal gas" is not enough. Gamma is 7/5 for diatomics and 5/3 for monatomic gases. Both can be ideal in terms of the gas law.

if you are paying money to take this course, you are beiung cheated.
