Answer 1

Answer:

less than.

Answer 2

Boiling point of pure water is less than that of impure water.

Explanation:

If the impurities are present then the amount of molecules which are available for vaporization get decreased.

When the water molecules are less then it will take more amount of heat to vaporize. This makes the rise in boiling point of pure water.

Also, impurities can lead lesser water molecules to get converted into vapor phase so the boiling point of pure water i.e. 100°C becomes less in comparison to the impure water.
