WebFeb 15, 2024 · And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The … WebThe transfer of heat goes from the hot object to the cold object. We could imagine a system in which the heat would instead be transferred from the cold object to the hot object, and such a system would not violate the first law of thermodynamics. The cold object would get colder and the hot object would get hotter but energy would be conserved. WebJan 22, 2024 · If heat transferred spontaneously from cold to hot the change would be < 0. This can easily be seen by assuming the two sources are thermal reservoirs (constant temperature sources). Then, if heat transferred from cold to hot you would have for the cold reservoir Δ S C = − Q T C And for the hot reservoir Δ S H = + Q T H screening printing office duties
