Heat Of Vaporization (Noun)
Meaning
Heat absorbed by a unit mass of a material at its boiling point in order to convert the material into a gas at the same temperature.
Classification
Nouns denoting natural phenomena.
Examples
- The heat of vaporization is an important thermodynamic property that affects the boiling point and vapor pressure of a substance.
- Measuring the heat of vaporization of a liquid allows scientists to determine the amount of energy required to turn the substance into a gas.
- At standard atmospheric pressure, the heat of vaporization of water is 2257 J/g, which indicates the energy needed to vaporize one gram of water into steam.
- The heat of vaporization varies significantly between different materials, with some substances requiring much more energy to change from liquid to gas than others.
- Understanding the heat of vaporization of different materials is crucial in various engineering applications, such as the design of refrigeration systems and distillation equipment.
