WebJan 15, 2015 · It transfers heat from the cold box (making it colder) to the warm air outside (making it warmer). It can do this because it is not a closed system . The way it is not closed is that it has energy input, which drives the pump. The air outside is doubly warmed - by the heat removed from the box, and by the heat of the energy that drives the pump. WebOct 31, 2024 · Make sure students realize that 1) heat is a form of energy that is transferred by a difference in temperature; a difference in temperature is needed for heat to flow, 2) heat always flows from hot to cold, or more precisely, heat flows from higher temperature to lower temperature, and 3) the units of heat are Joules, just like kinetic energy.
