A monatomic ideal gas that is initially at a pressure of 1.60×105Pa and with a volume of 8.50×10−2m3 is compressed adiabatically to a volume of 4.00×10−2m3

A) What is the final pressure? - 5.63E5

B) How much work is done by the gas during the compression?

C) What is the ratio of the final temperature of the gas to its initial temperature? - T2/T1 = 1.65



dU = -W
nCvdT = -pdV

The problem I am having is actually knowing how to determine work done in an adiabatic system outside of using the change in internal energy. I am at a loss of what to do.

How about dW = -pdV?

Make that pdV.
