03.48: Two completely idenxp vdbjh(9a66 ticalw.a ) 0aiubi jds/ so)tv9n+m9 samples of the same ideal gas are in equal volume containe/ . bv)jii9wtoa ss 9dan+)0umrs with the same pressure and temperature in containers labeled A and B. 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.
A. The gas in container A
B. The gas in container B
C. The gases have equal temperature
D. The value of the work W is necessary to answer this question.
E. The value of the work W is necessary, along with both the initial pressure and volume, in order to answer the question.
