Suppose that you have a basin of 35C warm water that you use to run a heat engine that cools its substance with air at 20C. What is the maximum efficiency of the heat engine? What is the work you get out of each kJ of heat extracted from the basin? Repeat for the case that the water is at 100C. Comment on why efficient car engines run so hot.
