Question

There is difference in boiling and freezing point of distilled and impure water . Give reason.

Answer 1

There is a difference in the boiling point and freezing point of impure and distilled water because the boiling point and freezing point of distilled water are 100°c and 0°c whereas the boiling point of impure water will be slightly higher than the normal temperature and the freezing point will also be lower than 0°c.This is because it takes more heat to change the water into vapour because of the impurities present.
