Question

Define: boiling point definition. the boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. therefore, the boiling point of a liquid depends on atmospheric pressure. the boiling point becomes lower as the external pressure is reduced.

Answer 1

ya it's right

boiling point =At this temperature the liquid starts changing into gas .The temperature at which a liquid starts boiling at the atmospheric pressure is known as boiling point.......

I hope you understand...........

Answer 2

at this temperature the liquid start changing into gas.
