The solubility of a salt in water is `40 g` at `30^(@)C`. The amount of water required to dissolve `120 g` at the same temperature is:

The solubility of K_(2)SO_(4) in water is 16 g at 50^(@)C . The minimum amount of water required to dissolve 4 g K_(2)SO_(4) is:

The solubility of K_(2)SO_(4) in water is 16 g at 50^(@)C . The minimum amount of water required to dissolve 4 g K_(2)SO_(4) is:

The amount of heat energy required to raise the temperature of 1g of water b 1^@C is called

At 30^(@)C , the actual amount of water vapour present in 1 m^(3) of air is 15 g, whereas 30 g of water vapour is required to saturate air at the same temperature. Find the relative humidity.

What would be the amount of heat required to increase the temperature of 1 g of water by 1^(@)C ?

The solubility curve of KNO_(3) in water is shown below. The amount of KNO_(3) that dissolves in 50 g of water at 40^(@)C is closest to
