2. The sketch below shows a perfectly insulated container with two compartments separated by a non-adiabatic, frictionless piston Both compartments are at the same pressure (pa= PB)and contain an equal amount of the same gas( ma =mB). Initially compartment a is at a higher temperature than compartment B(TA>TB2.
