"What is the function of a heat engine? a. It converts chemical energy to mechanical energy. b. It converts thermal energy to mechanical energy. c. It converts mechanical energy to chemical energy. d. It converts thermal energy into chemical energy."   Answer: What does a heat engine do? Heat engines convert thermal energy into mechanical energy, so the answer is the letter (b). Explanation: Heat engines generally work by using a rotating shaft that uses excess heat from a source such as a furnace in the old days and converting a bit of that heat into movement or work, the same process is in use today even with solar panels as a heat source.   Being dependent on cycles, heat engines need some sort of fluid (working fluid) to continue functioning.   It all starts with a heat source, where the heat generated will be absorbed by the fluid, converting itself into steam using a type of boiler. The expanded steam turns the shaft which is almost always a t...
