when water vapour condense it again turns into water. In order to do so it must release heat; the enthalpy of condensation is the negative of the enthalpy of vaporization (i.e. going from liquid to gas).

In classical mechanics, kinetic energy is distributed evenly between all degrees of freedom. Therefore the total kinetic energy is proportional to the number of degrees of freedom of the body.

Liquids particles have fewer degrees of freedom than those of gases. Upon the phase transformation, the extra energy is given off to a colder center of condensation - either a dust particle, or another, colder, liquid particle.

Yes, the latent heat of vaporisation will be released.

It looses energy. Because it is going into the air and is taking up a lot of energy.

What does water condenses into?

Water evaporates into water vapour, and water vapour condenses into water.

What happens to water during condensation?

The warm water vapour loses heat to the sky and condenses into water droplets, forming clouds.


How are weather systems dependent on water?

Because water vapour contains the latent heat of evaporation which is released back into the air when water condenses. It is this heat that drives the storms.


Why does condensation warm on a glass of icetea?

Condensation comes from water vapour in the atmosphere turning into liquid water. It took heat for the original water to turn into vapour, and that heat is still in the vapour. It is called latent heat. When the vapour condenses, that latent heat is given back and warms the glass.


When a cloud forms does the temperature of the atmosphere increase or decrease?

Increase:- When water vapour condenses out of the air to form water droplets, the energy (the latent heat) in the water vapour is released into the surrounding air and the air is warmed.


What happens to water vapors?

Water vapour evaporates due to heat and goes into the clouds. Then when the clouds cool the water vapour condenses and falls as rain <== I think :S


Why does dew form on a cold soft drink can?

Condensation forms on any cold container because heat is transferred from water vapour in the air near the container to it, which warms the container and cools the vapour. The vapour turns back to liquid and condenses on the container surface.


What happens when a liquid condenses?

I don't think you can condense a liquid, you can evaporate a liquid eg water which turnns into water vapour then when the water vapour gets colder it cools and condenses


How latent heat is an important source of atmospheric energy?

In the atmosphere latent heat is a property of water vapour. When water vapour condenses it releases latent heat, and latent heat must be supplied to evaporate liquid water. This heat affects the behaviour of the weather. Similar effects occur in the change from liquid water to ice and vice versa.


When vapour condense into a liquid?

If it happens in a cloud, the drops combine until too heavy, and it rains.
