b, it begins to boil. As a general rule, a higher vapor pressure is a lower boiling point. Vapor pressure goes...

Vapor pressure is the pressure exerted by evaporation of the liquid, while external P (usually atmosphereric) is the P of the surrounding air on the liquid.

.... At this point, the pressure the vapor is at is the equilibrium vapor pressure .

because there is air in the water. When the pressure is less outside the water than inside the water, the air wants to escape...
