**drwls**, Sunday, March 4, 2012 at 12:29amDoes the temperature stay the same? Or is this an isentropic (adiabatic) expansion? They need to tell you.

All you know is that pressure is decreased by a factor

R2/P1 = 7800/10130 = 0.770

If the process is adiabatic, they need to tell you what the gas is. (The "gamma" specific heat ratio is needed)
