The relative humidity on a day, when partial pressure of water vapour is `0.012xx10^(5)` Pa at `12^(@)C` is (take vapour pressure of water at this temperature as `0.016xx10^(5)` Pa)

The realativen humidity on day when partial pressure of water vapour is 0.12xx10^(6) Pa at 12^(@) C is (Take vapour pressure of water at this temperatue as 0.06xx10^(5) Pa)

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 .

10 Its of an air sample with relative humidity 0.6 is compressed to 5 litres at same temperature. What is the partial pressure of the water vapour in the compressed air, if the pressure of saturated water vapour at that temperature is 2.4 K Pa

10 litres of an air sample with relative humidity 0.6 is compressed to 5 litres at same temperature. What is the partial pressure of the water vapour in the compressed air, if the pressure of saturated water vapour at that temperature is 2.4 K Pa

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

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

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) .

On a certain humid day, the mole fraction of water vapour in air at 25^(@)C is 0.0287. If total pressure of air is 0.977 bar, calculate the partial pressure of water vapour in air and relative humidity if vapour pressure of water at 25^(@)C is 0.0313 bar.

Let P and P_(s) be the partial pressure of water and saturated partial pressure of water vapours, then relative humidity is given by .
