Heat flows from cooler to warmer objects
WebWhen the two systems are in contact, heat will be transferred through molecular collisions from the hotter system to the cooler system. The thermal energy will flow in that direction until the two objects are at the same temperature. When the two systems in contact are at the same temperature, we say they are in thermal equilibrium. WebIf we are talking about spontaneous heat flow, the second law of thermodynamics says that net heat flow is always from the warmer object to the cooler. That does not mean, …

Web12 de jul. de 2024 · Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time. While heat is transferred from A to B, B is radiating into universe, which should cause "other changes". So, there is no violation of the second law of thermodynamics. Web14 de abr. de 2024 · Global warming sceptics use the law to say that because the transfer of heat from the warmer surface of the earth to the cooler atmosphere is irreversible, global warming is impossible since the cooler atmosphere cannot heat up the warmer surface. This argument is reflected in Facebook posts here, here, here, and here.
