It tells us that a system can exchange energy with its surroundings by the transmission of heat and by the performance of work. The net energy exchanged is then equal to the change in the total mechanical energy of the molecules of the system (i.e., the system’s internal energy).

Web12 jan. 2024 · Assume that some energy Q is incident on both of them, and since they must maintain thermal equilibrium, they must emit as much heat as they absorb. One could write for A: E a = a Q, where a is the absorptivity of A. and for B: E b = Q. Some algebra gives E a E b = a. However, by definition, E a E b = e so a = e.
