I am only looking for help in part a.

2. Relevant equations

PV = mRT

3. The attempt at a solution

By looking at the figure, I was able to calculate the volume of state 2, which is half of the volume of state 1.

V1 = (mRT1)/P1

V1 = (5*0.287*573)/200

V1 = 4.11 meters cubed

V2 = V1/2

V2 = 2.06 meters cubed

However, in order to calculate the temperature by using the Ideal Gas Law, I need pressure first. How do I go about finding pressure? Is there an assumption I'm supposed to make first?
