A quantity of an ideal gas in an isolated system expanded isothermally and reversibly at 400 K from a volume V1 to a volume V2. During the expansion, the gas absorbs 200 J of heat from the reservoir in contact with it. Suppose the gas expanded volume V1 to a volume V2 isothermally but irreversibly at 400 K and absorbed 100 J of heat. What will be (a) the entropy change of the gas; (b) the entropy change of the reservoir, and (c) the entropy change of the whole system. Answer: (0.50, -0.25, 0)
