1. The problem statement, all variables and given/known data 'A closed cylinder containing a perfect gas at 300K is divided into two parts A and B of equal volume, V0 by a freely moveable close-fitting piston. The gas in B is then heated to 400K but that in A is maintained at 300K. Show that the final volume of the gas in B, Vbf = 8/7V0.' 2. Relevant equations P1V1/T1=P2V2/T2 P1V1=P2V2 2V0-Vaf=Vbf 3. The attempt at a solution Not really sure, just continually messing about with the above equations with no substantial progress. Obviously two equations, one for Gas A and Gas B. Would really appreciate any help, thanks.
