Review QAS a. Energy transfers by heat are induced only as a result of a temperature difference between a system and its surroundings. b. Work and heat are associated with the process, so they are point functions C. If a system undergoes a process involving heat transfer with its surroundings but no work, that process is said to be adiabatic. d. The change in the internal energy of a system between two states is the...
