During the isothermal heat rejection process of a Carnot cycle, the working fluid experiences an entropy change of -1.3 kJ/K. If the temperature of the heat sink is 35C, determine (a) the amount of heat transfer, (b) the entropy change of the sink, and (c) the total entropy change for this process.
