Systems and Transfer of Energy

APCHEM-V5LTJL

Presume each system in the graphic below has the same density.

Which of the following accounts for the transfer of energy between the two isolated, non-reacting systems where T1 > T2?

A

The temperature change between the two systems is the same in magnitude.

B

The energy transfer between the two systems is the same in magnitude but opposite in sign.

C

Even though energy is lost to the surroundings, the overall energy of the system is conserved.

D

The average kinetic energy of the two systems is generally higher than the average kinetic energy of either system individually.
