Question

The boiling point of a liquid decreases by the addition of impurities to it.

• A. True
• B. False

Answer 1

The correct option is B

False

The boiling point of liquids increases by the addition of impurities to it. If a little common salt is added to the water, it boils at a temperature higher than 100 degree Celsius. This is why on the addition of salt while cooking, water provides sufficient heat energy to its contents before boiling. Therefore the cooking of food becomes easier.
