Heat Of Fusion (Noun)

Meaning

Heat absorbed by a unit mass of a solid at its melting point in order to convert the solid into a liquid at the same temperature; "the heat of fusion is equal to the heat of solidification".

Classification

Nouns denoting natural phenomena.

Examples

  • The heat of fusion for water is approximately 334 joules per gram at its melting point of 0 degrees Celsius.
  • Ice's relatively low heat of fusion makes it seem solid at a higher temperature in the presence of air with high humidity.
  • Using the principles of thermodynamics, one scientist measured the heat of fusion of various crystalline substances to compare their solid-liquid phase transitions.
  • In general, a substance with a higher heat of fusion requires a greater amount of heat energy to change it from a solid into a liquid.
  • Because of its heat of fusion, it takes more heat energy to melt the solid wax than it does to change its liquid state to the gaseous state.
