Question #c64fe

1 Answer

The answer has to do with Vapor Pressure.


Vapor pressure is the measure of the force exerted by a gas that is above a liquid. Vapor pressure changes with temperature, and the boiling point of a substance (at liquid state) occurs when the liquid reaches the same pressure as the gas around it, by an increase in its temperature. This works because of Gay-Lussac's gas law which relates rising temperature to rising pressure ( P1/T1=P2/T2 ).
