Hot air rises, so is lighter than cold air.
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 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.
Because cold air is more dense, and also contains less water vapour.
Nitrous Oxide is heavier than air.
Some are heavier, but some are lighter. For example, methane rises but propane sinks.
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
Cold air is heavier
Water because a liter is a measurement of space and not mass. Water occupying 1 liter of space is lots heavier than air occupying 1 liter of space. <><><><><> It depends on density. It is possible, given enough pressure, to have one liter of air weigh more than one liter of water.
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.
Water
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
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.
