Question #176361

WHAT IS IT IN MOLAR HEAT OF VAPORIZATION

- Keep in mind the fact that this is very specific value. It is only for one mole of substance boiling. The molar heat of vaporization is an important part of energy calculations since it tells you how much energy is needed to boil each mole of substance on hand. ( Or, if were cooling off a substance, how much energy is required per mole in order to remove from a substancr as it condenses.)

Ethanol ;

As alcohol evaporates at a much faster rate compared with water due to its lower boiling temperature, it is able to carry away more heat from the skin. This means for a given amount of time much more alcohol evaporates than water.
