1. The problem statement, all variables and given/known data
A tank is equally divided into two equal halves, one a vacuum and one filled with argon gas at 298K and 700 bar. The divider bursts and the gas equally disperses throughout the tank. What is the new T and P of the gas assuming argon is an ideal gas? 2. Relevant equations PV=nRT P1V1/T1=P2V2/T2 3. The attempt at a solution I assumed there was no temperature change which I am unsure of but using that logic, P=350 bar and T=298K

Begin with the definiton of an ideal gas. Hint: it's more than just pV = nRT.
What can you say about the dependence of U, internal energy, as a function of p,V and/or T? Then go with the first law and show that you get the same results whether the free expansion is adiabatic or isothermal or anything inbetween.
