Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body warming up. This is a natural phenomenon we experience all the time.
WebJul 29, 2008 · This is what the second law of thermodynamics says. It says that heat flows from body at high temperature to the body at low temperature. If you want to transfer heat from low temperature to high temperature body, external work has to be done. The major application of second law of thermodynamics is observed in the field of HVAC where the … WebMay 13, 2024 · The first law of thermodynamics defines the relationship between the various forms of energy present in a system (kinetic and potential), the work which the system performs and the transfer of heat. The first law states that energy is conserved in all thermodynamic processes.
