A heat source is a body or substance that provides thermal energy to another body, typically through the transfer of heat due to a temperature difference. This term is crucial in understanding various thermodynamic processes, as it plays a key role in the functioning of heat engines and cycles, such as the Carnot cycle. The effectiveness of a heat source is often characterized by its temperature and the amount of energy it can supply, which directly influences the efficiency of thermal systems.
