Aheat engine question 6 options: changes mechanical energy to thermal energy changes mechanical energy into electrical energy changes thermal energy into mechanical energy changes kinetic energy into thermal energy

Changes thermal energy into mechanical energy.

Explanation:

A heat engine changes thermal energy into mechanical energy.

Heat Engine changes thermal energy into mechanical energy.

Option C

Explanation:

An heat engine is an engine which converts the thermal energy to the mechanical form of energy through the combustion of the heat. Combustion of heat liberates heat energy which causes increase in pressure which serves as a force for the mechanical energy.

The energy conversion is used to do mechanical work. It is obtained by conversion from higher state temperature to lower state temperature.
