I have 5.00 mol of O2(Oxygen) at 20.0 Celsius and 1.00atm. I will compress this to 1/10 the original volume. Find the work? The correct answer is 46.1 Kj I am having a terrible time with this. This is what I know: Q = 0 for an adiabatic process, and the change in internal energy is equal to work. I think I use integrate Pdv, but Im getting very confused. I am really lost and need a push in the right direction!
