Indicate your answer by a check mark in the appropriate column next to the statement. True False 1. A bag of sand is dropped from a height of 10 m onto a level pavement. As the bag strikes the pavement, it does no configuration work ( PdV ), but its entropy increases. 2. In separate experiments, 1 m 3

Unformatted text preview: of oxygen gas undergoes an isothermal expansion, doubling its volume in each case. The first experiment involves an adiabatic free expansion. In the second experiment, the gas does configuration work while in thermal contact with its surroundings. The entropy of the gas increases in the second experiment, because it absorbs heat from its surroundings. In contrast, there is no heat flow in the first experiment, so the entropy of the gas must remain constant. √...
