What is the term used to describe the amount of heat required to change a liquid into a solid?

The term used to describe the amount of heat required to change a liquid into a solid is known as the latent heat of fusion. This process occurs when ice forms from water, and temperature remains constant during the phase change until the entire liquid has solidified. During this transformation, heat is released into the surrounding environment even though the temperature does not change.

Latent heat of fusion specifically refers to the energy released when a substance transitions from a liquid to a solid state, highlighting the energy dynamics involved in phase changes. Understanding this concept is crucial in ice facility operations, as managing the heat exchange is essential for maintaining the quality of ice and the efficiency of the freezing process.
