Interpretation: The amount of ethanol vaporizes on transferring 5000 cal is to be calculated.
Concept introduction: The quantity of heat needed to convert 1 mole of liquid to a gas at its boiling point is termed as enthalpy of vaporization. There are many units of expressing the heat, such as calories,
