Heat energy can be converted into mechanical energy through the process of thermal expansion (e.g., steam engines) or by using it to drive a turbine that generates movement (e.g., power plants). In the case of converting heat energy into electrical energy, this can be achieved through thermoelectric generators that utilize the temperature difference to produce electricity.

What is the maximum amount of mechanical energy that can be converted to heat?

The maximum amount of mechanical energy that can be converted to heat is equal to the total mechanical energy input. In any conversion process, there will always be losses due to inefficiencies, so the actual amount of mechanical energy that is converted to useful heat will be less than the input mechanical energy.
