Which of these types of motors or engines are heat engines?
a. an automobile engine
b. an electric motor
c. a steam turbine
Heat engines produce mechanical or electrical energy from heat. That excludes electric motors from consideration.
A steam turbine can in some cases be one PART of a heat engine, but a burner, geothermal source or nuclear reactor would have to be part of the complete heat engine system.
