The normal boiling point of a substance is defined as the temperature at which the vapour pressure above the liquid equals the external pressure, which is one atmosphere (1 atm) or simply the temperature at which the substance boils at 1 atm. Standard pressure is 1 bar, so the standard boiling point is the temperature at which the substance boils at 1 bar. The normal boiling point for ethanol is 78.4 ∘C. Given that the heat of vaporization for ethanol...
