WebFeb 15, 2024 · Does cold transfer like heat? The transfer of heat goes from the hot object to the cold object. The cold object gets colder and the hot object gets hotter, but energy is conserved. Why does heat make molecules move? When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms … WebMar 19, 2024 · If heat heat were to flow from a cold to hot object, the heat lost by the cold object would equal the heat gained by the hot object and the first law would be satisfied. But since this never happens, a new law was needed that made such a flow of heat impossible . ... Where the equal sign applies to a reversible transfer of heat, i.e., when the ...
