(adsbygoogle = window.adsbygoogle || []).push({}); 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
