This floating effect is known as a displacement force or buoyant force ... WebJun 28, 2004 · Chroot is correct, hot air rises because it occupies a greater volume per unit mass of air than cooler air. It is simply an application of Archimedes principle. Incidentally, if the volume remained constant as the temperature rose, then according to GR/SR since energy is a mass equivalent the hotter body would sink rather than rise. Jun 24, 2004 #5
