Which reverses the normal flow of thermal energy? a. steam engine b. heat pump c. combustion engine d. refrigerant

Heat pump

Explanation:

heat pumps reverse the normal flow of thermal energy and are part of refrigerants and air conditioners. This is a device that transfers the heat from source to sink.

How the work?

They move thermal energy in a direction that is just opposite to its spontaneous heat transfer. They absorb the heat energy from cold space and then discharge that heat into a warm space.They use external power to do the heat transfer work.
