Question
The heat capacities of the source and the sink should be infinite. Why so?
✓

Answer

The heat capacity of the heat source should be infinite so that the heat taken by the heat engine does not heat the source and its temperature remains constant. The heat capacity of the sink should also be infinite so that its temperature does not increase due to the heat given up by the heat engine and remains constant.
