What is boiling point? What is freezing point?
(N/A) $1$. Boiling point: The boiling point of a liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure $(1.013 \ bar)$.
$2$. Freezing point: The freezing point of a substance is the temperature at which the vapor pressure of the substance in its liquid phase is equal to the vapor pressure of the substance in its solid phase.
