Study Notes
Latent Heat of Fusion
- Definition: The quantity of heat required to change one unit mass of a substance from solid to liquid at its melting point.
- The amount of heat is called the latent heat of fusion.
Latent Heat of Vaporization
- Definition: The quantity of heat required to change one unit mass of a substance from liquid to vapor at its boiling point.
- The amount of heat is called the latent heat of vaporization.
Heat Transfer Methods
- Conduction: Heat transfer from one end to another without particle movement.
- Convection: Heat transfer involving the movement of materials, such as air or water.
- Radiation: Heat transfer without a medium, for example, from the sun to Earth.
