They do work, they use the Stefan-Boltzmann law (related to radiation of hot bodies)

Heat, work, and internal energy are all forms of energy transfer. Heat is energy transfer due to a temperature difference, work is energy transfer due to a force acting through a distance, and internal energy is the total energy of a system. The change in internal energy of a system is the sum of the heat added to the system and the work done on the system.
Define Heat of Work and Explain how it is computed.Heat of Work (HOW) is the the amount of heat added to refrigerant during the compression process. The heat content of the refrigerant at the outlet of the compressor (high-side) is subtracted from the heat content at the inlet of the compressor (low-side). The unit of measurement is in Btu/lbAnswerThere is no such thing as 'heat of work'. Heat and work are two different, but related, things. 'Heat' describes energy in transit from a higher temperature to a lower temperature, whereas 'work' describes energy in transit when one form of energy is converted into another form. The difference between work and heat is a measure of the rise in the internal energy of an object.
Heat is generally considered as a resultant of other energy reactions, which is why it is considered to be related to kinetic energy. All types of energy (the ability to do work) can produce heat energy.
No, a heat engine is not a device that converts work into heat. It is the opposite, which means it is a device that converts heat into work.

Thermal energy is energy that is related to heat and the temperature of matter.
