The warmer the air is, the more energy the molecules have. The more energy the molecules have, the more they vibrate. When the molecules vibrate, they bounce into each other and push apart from each other, hence the warmer the air is, the less dense it is (number of molecules per unit volume). Colder air has less energy which means more molecules can fit into one space because they are not bouncing off each other.

So, colder air has less energy which means more molecules can fit into one space (because they are not bouncing off each other).

Density. You can figure out the details using the ideal gas law.
A warm air mass rises over a cold air mass at a warm front because warm air is less dense than cold air. This results in the warm air mass being forced to rise and cool, leading to the formation of clouds and precipitation at the boundary of the two air masses.
Differing air temperature causing cold air to sink, and warm air to rise is the main cause of air movement.
The cold air will sink.
Cold dye is denser than warm water, so it sinks instead of rising. When cold dye is added to warm water, it stays at the bottom because the warm water is less dense and stays on top. This difference in density causes the cold dye to remain submerged in the warm water.
cold air sinks as denser - warm air rises
Cold will sink to the bottom. Hot water will rise to the top.
The process is called convection. Warm molecules rise because they are less dense and cold molecules sink because they are more dense. This movement of fluids helps redistribute heat in a system.
Density. You can figure out the details using the ideal gas law.
Warm air rises because it is less dense than cold air, due to the expansion of its molecules. Cold air sinks because it is more dense than warm air, as its molecules are more closely packed together. This movement creates convection currents as the warm air replaces the cold air.
Warm air rises because it is less dense than cold air, creating an upward movement. As warm air rises, it cools down and becomes denser, then sinks back down. This cycle of warm air rising and cold air sinking creates convection currents.
Convection is the process that causes warm air to rise and cold air to sink. As such, the winds caused by this process are called convection currents.
Cold dye is denser than warm water due to differences in their molecular structure and temperature. When substances are more dense than their surrounding environment, they will sink rather than rise. As a result, the cold dye will stay at the bottom of the warm water instead of rising to the top.

Cold water is more dense than warm water so the cold water has to sink to the bottom which causes a density current.
