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....
