What is the amount of heat required to vaporize one mole of a liquid at constant temperature and under standard pressure (1 bar) called?

Options

  1. AStandard enthalpy of sublimation
  2. BStandard enthalpy of fusion
  3. CStandard enthalpy of vaporization or molar enthalpy of vaporization
  4. DStandard enthalpy of condensation

Correct answer

C. Standard enthalpy of vaporization or molar enthalpy of vaporization

Step-by-step solution

The amount of heat required to vaporize one mole of a liquid at constant temperature and under standard pressure (1 bar) is called its standard enthalpy of vaporization or molar enthalpy of vaporization, ∆ vap H.
