Pure water vapour is trapped in a vessel of volume `10cm^(3)`. The relative humidity is 40%. The vapour is compressed slowly and isothermally.find the volume of the vapour at which it will start condendsing.

If saturated vapours are compressed slowly (temperature remaining constant) to half the initital volume, the vapour pressure will

If saturated vapours are compressed slowly (temperature remaining constant) to half the initital volume, the vapour pressure will

Write the volume of vapour of 1 g water at 1 atmospheric pressure.

How much water vapour is contained in a cubic room of 4m along an edge if the relative humidity 1s 50% water at 27^(@)C The vapour pressure of water at 27^(@)C is 26.7 torr (The relative humidity expresses the partial pressure of water as a per cent of water vapour pressure) .

True or False : Water vapour content of air is measured by relative humidity.

If saturated vapours are compressed slowly (temperature remains constant) to half the initial volume, their pressure will be constant. give reason

If there is no intermolecular force, what will be the volume of 4.5 kg water vapour at STP ?

true or false: Water vapour content of air is measured by relative humidity.

A cylinder closed by a piston contains 8 g of water vapour at a temperature of 55^(@)C . The vapour is compressed isothermally. What will be its volume when dew begins to appear?

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
