Why Does Hot Air Rise & Cold Air Sink? …

WebApr 17, 2024 · Why does hot air or warm air rises upwards? The faster molecules move, the hotter the air. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. Does cold air rises or sinks? WebAs you say, masses m are constant but volumes usually grow with higher temperature. That hot air molecules will float up is not do to any changes in mass or so - but to changes in … marky skin condition
