A barometer tube is 80 cm long (above the mercury reservoir). It reads 76 cm in a particular day. A small amount of water is introduced in the tube and the reading drops to 75.4 cm. Find the relative humidity in the space above the mercury column if the saturation vapor pressure at the room temperature is 1.0cm.

The temperature and the relative humidity of air are 20^(@)c and 80% on a certain day. Find the fraction of the mass of water vapour that will condense if the temperature falls to 5^(@)C .The saturation vapour pressure are 17.5mm and 6.5mm of mercury at 20^(@)c and 5 degree C respectively.

Dry air : less than 60% Relative humidity :: Humind air. …..

On a winter day, the outside temperature is 0^(@)C and relative humidity 40%.The air from outside comes into a room and is heated to 20^(@)C. What is the relative humidity in the room? The saturated vapour pressure at 0^(@)C is 4.6mm of mercury and at 20^(@)C it is 18mm of mercury.

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.

The temperature and the relative humidity are 300 K and 20% in a room of volume 50 m^(3) . The floor is washed with water, 500 g of water sticking on the floor. Assuming no communication with the surrounding, find the relative humidity when the floor dries. The changes in temperature and pressure may be neglected. Saturation vapour pressure at 300 K = 3.3 kPa .

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 .
