We can imagine a system, however, in which the heat is instead transferred from the cold object to the hot object, and such a system … Web1 Answer. Heat does not rise or sink because it isn't actually a substance, it's energy being transferred. It is hot air which rises. The reason for this is that hotter air is more dilute than colder air. Or equivalently: colder air is denser than hotter air. The temperature of the air only plays a secondary role in determining which layer will ...
WebAug 9, 2024 · In general, heat will move from a warmer object to a cooler object, but there are some exceptions to this rule. One of the most common misconceptions about heat is that it always rises. In reality, the direction that heat travels depends on the temperature difference between the objects. If the difference is small, then the heat will move from ... WebMar 19, 2024 · Heat always flows from higher to lower temperature and so the direction of heat flow was just a matter of definition.
