Hot air is less dense than the surrounding air and therefore it rises. Cold air, on the other hand, is the opposite. It is more dense than surrounding air and sinks.

∙ 12y agoBecause hot air is less dense (lighter) than cold air. Cold air is denser (heavier) than cold air. Another word for this is evaporation.

How does cold temperature affect density?
there is a property called convection which applies to liquids and gases. that property says colder liquids or gases are denser.
How can liquids become gases and gases become liquids?
vaporization
What happens to the solubility of gases when temperature is increased?
Solubility of gases in liquids decreases with increase in temperature. When gases are dissolved in liquids, heat is evolved. Following Le Chatelier's principle, as the temperature increases, the solubility decreases. This is the reason that aquatic species are more comfortable in cold water as compared in warm water.
Gases can be squashed compressedbut solids cannot?
Flow. Gases and liquids can both modify their shapes.
How does pressure affect the solubility of gases in liquids?
Increasing the pressure, the solubility of gases in liquids is increased.
Does atoms and molecules of gases and liquids are heated they sink?
after atoms and molecules of gases and liquids are heated, they sink?
When gases or liquids rise and sink in a circular path?
Convection current
What is a current when solids gases or liquids rise and sink in a looping path?
Convection
Do gases dissolve best in cold liquids?
Yes

What produced when gases or liquids rise and sink in a circular path due to temperature differences?
Convective mixing.
What is produced when gases or liquids rise and sink in a circular path due to temperature differences?
Convective mixing.
Does a jet stream or convection current cause gases and liquids to rise and sink in a circular path?
Convection current
How are gases and liquids alike?
liquids and gases both have an Indefinite shape. nd some liquids turn into gases with heat.
Which substances can heat travel through by convection?
Fluids, aka liquids and gases.
How can liquids become gases and gases become liquids?
vaporization
In what way are liquids and gases alike?
Liquids and Gases are both matter, and are not solids.
