Study Notes
Molar Enthalpy of Vaporization and Fusion
- Molar enthalpy of vaporization is the energy required to change 1 mole of a substance from a liquid to a gas at constant temperature and pressure.
- Molar enthalpy of fusion is the energy required to change 1 mole of a substance from a solid to a liquid at constant temperature and pressure.
- Both molar enthalpy of vaporization and fusion are typically measured in units of kJ/mol.
- Molar enthalpy of vaporization and fusion are often used to describe the energy changes associated with phase transitions.
- Molar enthalpy of vaporization and fusion are important thermodynamic properties that can be used to understand the behavior of substances in different physical states.
