The boiling point of a substance is the temperature at which the substance boils, or enters a state of rapid evaporation. For pure water this is 100° Celsius.

Answer 2

Answer:

Boiling point is a temperature of a liquid at which vapour pressure of liquid becomes equal to the atmospheric pressure.

Vapour pressure is the pressure exerted by vapours of the liquid when the rate of vapourization becomes equal to the rate of condensation at a particular temperature.

The boiling point of water is 100°C at 1 atmospheric pressure
