How does boiling point elevation occur
WebThe boiling point of a liquid is the temperature at which the vapor pressure of the liquid is the same as the atmospheric pressure above the liquid. If we can artificially increase the vapor pressure of the liquid, we decrease the boiling temperature. WebA liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. The Macroscopic View As a liquid is heated, its vapor pressure increases until the vapor pressure equals the pressure of the gas above it.
