Question

Which term is used to describe the amount of heat that is required to convert 1 mol of a liquid to a gas?

A. dew point

B. boiling point

C. molar heat of fusion

D. molar heat of vaporization

Answer 1

The answer is Letter D. molar heat of vaporization, B is also right, boiling point. Boiling point has vaporization. Regardless If you want to Pass pick Letter D, it's right if on e2020. God Bless you and your familys'! 

Answer 2

Answer is: D. molar heat of vaporization.

For example, evaporization is phase change process in which the water changes from a liquid to a gas (water vapor).

The dew point is the temperature to which air must be cooled to become saturated with water vapour.

Molar heat of fusion is the amount of heat that is required to melt 1 mol of a substance.

Liquids boil when their vapor pressures reach the external pressure. The boiling point of a liquid is the temperature at which its vapor pressure is equal to 1 atm.
