A bucket full of water is placed in a room at `15^(@)C` with initial relative humidity 40%. The volume of the room is `50m^(3)`.(a) How much water will evaporated? The saturation vapour pressure of water at `15^(@)C`and `20^(@)C`are 1.6kPa and 2.4 kPa respectively.

The vapour pressure of water in at 20^(@)C is 12mm of Hg on a particular day the sturation vapour pressure of water at 20^(@)C is 17.5 mm of Hg Calculate relative humidity .

The condition of air in a closed room is described as follows. Temperature =25^(@)C ,relative humidity=60%, pressure=104 kPa. If all the water vapour is removed from the room without changing the tempareture what will be the new pressure?The saturation vapour pressure at 25^(@)C=3.2 kPa .
