WebApr 28, 2024 · Heat flows from hot to cold because warmer molecules move faster. When warmer molecules bump into cooler ones, two things change: cooler molecules speed up (get warmer), and warmer molecules slow down (get cooler.) The flow of kinetic energy from warmer objects to cooler objects is “conduction.”. 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.
