It is not heavier, it is "denser" that is because its molecules move around less and thus take up less space.
False because warm air rises. The particles in cold air are moving more slowly and make cold air more dense than warm air.
Gas is heavier than oxygen. Cold air is heavir than hot air
Hot air rises, so is lighter than cold air.
Cold air is heavier
Cold air is heavier than warm air because cold air has higher density. This is because the molecules in cold air are closer together, leading to a greater mass per unit volume compared to warm air.
You have forgotten one vital fact, cold air is heavier than hot air------At the same atmospheric pressure!!. That means that the cold air on Mt Everest is lighter than than the warm air 29000 ft below in the Ganges Delta.
no cold air is heavier because it sinks and hot air rises
Air is heavier in warmer weather than in winter. This is because warm air is less dense than cold air, causing it to weigh more in the same volume compared to cold air.
cold air is heavier than hot air so the cold air gos to the hot air where theirs less pressure
the cold air is making the water in your hair cold which makes your hair cold. if your hair is dry then there is no water in i for the hair to be as cold as it is when its wet.
Cold air masses are denser and heavier than warm air masses. This is because cold air is more compact and contains more molecules per unit of volume, leading to higher air pressure compared to warm air masses.
Cold air has a high pressure because it is heavier than warm air.
