Because it's less dense. This means that the molecules are more spread out, so they rise.
When a warm front moves into a cold front, the warm air gradually rises over the denser cold air. This can lead to the formation of clouds and precipitation. The warm air displaces the cold air, leading to a gradual increase in temperature and humidity.
In cold air masses, the air is denser and tends to sink, bringing cooler temperatures and often creating stable conditions. In warm air masses, the air is lighter and tends to rise, leading to warmer temperatures and potentially creating more unstable weather conditions such as thunderstorms.
Warm air naturally goes up/rises and cold air has to make a current where it can go until it reaches a warm current which is under the warm air.
Temperature inversion occurs in the troposphere when warm air sits on top of cold air, causing the normal temperature profile to invert. This can lead to pollutants being trapped near the surface, affecting air quality. Temperature inversions are more common during calm, clear nights.
Yes, cold air tends to sink because it is denser than warm air. As it sinks, it displaces the warm air, causing it to rise. This creates a cycle of air circulation where cold air moves downward and warm air moves upward.

The reason why the top floor of a mall is warm is that warm air is less dense than cold air and so it rises while cooler air tends to drop down.
Warm air is lighter than cold air. So you'll always get warm air on top of cold air when they meet.
Because warm air is lighter then cold air. So warm air will raise (to the top of the room) and cold air will stay down. When the warm air is cooling down it lowers and when cold air is heated/heating up it raise.
Air movement can occur from warm to cool or cool to warm, depending on the temperature gradient between the two air masses. In general, air moves from areas of higher pressure to lower pressure, which can influence its temperature.
because convection causes the warm air to rise. This creates a cycle where the warm air moves to the top of the room.
This temperature difference in a refrigerator is due to the way the cooling system is designed. Cold air sinks, so the bottom of the refrigerator, where the vents are usually located, is cooler. Meanwhile, the top shelves are warmer because they are farther away from the cooling source and are impacted by warm air that rises.

Warm air close to the ground rises and becomes cooler.
Warm gases and warm fluids rise to the top. Same principle that makes hot air balloons fly.
Warm air always wants to move towards cooler air, as it seeks to balance out the temperature difference.
Cold air is more dense than warm air and therefore heavier
