Relative humidity of air is `60^(@)C` and the saturation vapour pressure of water vapour in air is `3.6kPa`. The amount of water vapours present in `2 L` air at `300 K` is

The saturation vapour pressure of water at 100^(@)C is

Name the physical quantity used to express the amount of water vapour presentin air.

How will you demonstrate that water vapour is present in air ?

When in air said to be saturated with water vapour ?

Condensation of water vapour in the air leads to the formation of ice.

Relative humidity id defind as the ration of partial pressure of water in air at a given temperature to the vapour pressure of water at that that temperature Calculate the mass of water per litre air at (a) 20^(@)C and 45% relative humidity (b) 0^(@)C and 95% relative humidity (c ) Discuss wether temperature or relative humidity has the greater effect on the mass of water vapour in air Given P_(H_(2)O)^(@) =17.5 torr at 20^(@)C and 4.58 torr 0^(@)C .
