Is cold air more or less dense than hot air
WebDec 16, 2024 · Cold air has higher density than the hot air because at the low temperature, the separation between the molecule of the gas is less. As, temperature increases the separation between the molecules of gas also increases and its density decreases. Why does air become less dense as it is warmed?
