I think your temperature is inverted. 5 should be temp for p2 and 20 be temperature for p1
Isnt 5 suppose to be for 0.28bar?

Sorry I didn’t read properly. 0.28bar is the external pressure and 5 is the external temp. But what you are interested in is the internal pressure and internal T.
Your comparison should also be the internal. Cause only internal moles of gas and volume of gas is remaining constant

Ohh ok thks!! Btw, how we decide whether to use this method or pV=nRt for similar qns?
You can always use PV=nRT.
The method you and I used on this question , it’s only when p,V,n,T, 2 of the variables are constant. Like for this case, n and V are constants.
So that’s why you can say p is proportional to T.
