As a 1.00 mol sample of a monoatomic gas expands adiabatically the work done on it is

-2.50x10^3J. The initial temperature and pressure of the gas are 500k and 3.60atm. Calculate

a. The final temperature and b. The final pressure.

2. Relevant equations

First law of thermodynamics

Eint = Q + W

3. The attempt at a solution

I was able to solve the first part of the question. Since it was an adiabatic process Q = 0 and then used Eint = nCv(Tb - Ta) to get the final temperature which is 300k.

But i can't seem to get the final pressure. I have no idea on how to begin. Please any help will be very much appreciated.
