Boiling Point

• The temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid.

• The temperature at which the pressure of the vapor in the solid is equal to the external pressure acting on the surface of the solid.

• The temperature at which the pressure of the vapor in the gas is equal to the external pressure acting on the surface of the gas.
