The enthalpy change which occurs when a solid is melted is called the heat of fusion. |
This freezing action releases the latent heat of fusion, so that the temperature of the water returns toward the freezing point. |
Glauber's salt remained in the short list since it has a high reported latent heat of fusion and thermal conductivity. |
When this surface layer is cooled to the ice point, 0 °C, ice is formed as the latent heat of fusion is extracted. |
The heat required to balance loss to the atmosphere, and hence to maintain the open water, is provided by the latent heat of fusion of the ice which continually forms. |
The latent heat of fusion, if the polymer is crystalline. |
