Finding final temperature

1. The problem statement, all variables and given/known data
The drawing shows an adiabatically isolated cylinder that is divided initially into two identical parts by an adiabatic partition. Both sides contain one mole of a monatomic ideal gas (), with the initial temperature being 523 K on the left and 287 K on the right. The partition is then allowed to move slowly (i.e. quasi-statically) to the right, until the pressures on each side of the partition are the same. Find the final temperatures on the (a) left and (b) right sides.

2. Relevant equations
I think that for this kind of problem i need to use W=3/2nRT, however I am not given any of the other variables so i am lost.


3. The attempt at a solution

How do pressure and volume relate during an adiabatic process? Look it up!
