In this regard, does cold air go up or down?
Cold air flows downward according to hot air because it is more dense and sinks while hot air rises. In hot room the air will be much thinner thus reducing the pressure so the air flows from cold room to hot rooms.
Also, is cool air heavier than warm air? Cold air is denser than warm air. The molecules are packed closer together. The more water vapor that is in the air, the less dense the air becomes. That is why cold, dry air is much heavier than warm, humid air.
Furthermore, does cool air rise?
Hot air is less dense than cold air, which is why hot air rises and cold air sinks, according to the United States Department of Energy. Hot and cold air currents power the weather systems on earth. Warm air currents typically bring rain, because they form over oceans.
Which way does warm airflow?
Air flows from higher pressure to lower pressure and the density of warmer air is lower than cold air. So the hot air rises and cold air sinks. Heat will flow from high thermal energy to low thermal energy—that is, a particle with a lot of energy will give some of that energy to a particle with less energy.
