Homework Statement
An ideal diatomic gas undergoes an adiabatic compression. Its initial pressure and volume are 1.20 atm and 0.200 m^3 and its final pressure is 2.40 atm. How much work is done by the gas?
Homework Equations
[itex]W = -\int p \cdot dV[/itex]
The Attempt at a Solution
So after integrating I got: [itex]W = -pV^{\gamma} \cdot \frac{{V_f}^{1 - \gamma} - {V_i}^{1 - \gamma}}{1 - \gamma}[/itex]
My first question: How do I know what [itex]pV^{\gamma}[/itex] is? Do I use the final pressure and volume for this constant term?
Second: How do I find [itex]V_f[/itex]? I don't see any equation I can use to solve for it using only final pressure.
