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 ... WebWelcome to FactTap!
