no its just air cooling around you which forms water vapour on the window


Why can you see clouds but not water vapour in the air?

It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.


What refers to the amount of water vapour in the air?

Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.


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.


Is Water vapor condensed steam.?

Yes. Steam is the gaseous form of water, and it is invisible. When it meets the colder air it starts to condense, and forms water vapour, which is visible.


What is occurring when you can see your breath on cold days?

The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.


Is water vapour not one of the constituents in air?

Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour


What is the name for gaseous water in the air?

water vapour


What is the name for the water gas in the air?

Water vapour.


Why does dew appear in early morning and not at noon?

the air capacity for holding water depends on temp'. the warmer it is the more water vapour it can hold. during the night air temp' drops to its lowest near dawn at which point the amout of water vapour in the air may exceed its reduced capacity (this point is called the dew point) and water vapour condences and forms dew.
