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.

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 .

A glass contains some water at room temperature 20^(@)C .Refrigerated water is added to it slowly. When the temperature of the glass reaches 10^(@)C, small droplets condense on the outer surface. Calculate the relative humidity in the room. The boiling point of water at a pressure of 17.5mm of mercury is 20^(@)C and at 8.9mm of mercury is 10^(@)C .

Select the correct statements. ( I ) Greater is humidity, lesser will be rate of evaporation of water. ( II ) Greater is humidity, lesser will be density of air. ( III ) If room temperature = dew point, realtive humidity = 100% . ( IV ) Dew point is the temperature at which the gas a given atmospheric condition becomes staturted with H_(2)O ( v )
