After the processes are performed on the gases in containers A and B, which is at the higher temperature?
The gas in container A performs non-zero work W on the surroundings during an isobaric (constant pressure) process before the pressure is reduced isochorically (constant volume) to 1/2 its initial amount.
The gas in container B has its pressure reduced isochorically (constant volume) to 1/2 its initial value and then the gas performs non-zero work W on the surroundings during an isobaric (constant pressure) process.
