This is latent heat. When a liquid freezes heat is released, and when it melts the same amount of energy must be supplied. Similarly when a liquid changes to a vapor, or when a vapor condenses, heat must be supplied or is released. Latent heat varies from one substance to another, and can be quantified as so many calories per gram or kilogram, you can find data in reference tables

∙ 11y agoenergy is released during freezing because particles in a liquid have more energy than particles in a solid

∙ 13y agoQuite obviously, its getting colder (exothermic) which means its releasing heat.

Which of the processes of water cycle occur to releaseing energy?
In the water cycle heat energy is released during the processes of condensation and freezing. 334 J/g is released during freezing and 2260 J/g is released during condensation.
Why does salt ice melt slower than ice with no salt?
The freezing point of water is lower with added salts; the heat of solution is released.
The amount of energy released by one kilogram of a substance at its freezing point?
Heat of Fusion
Is heat supplied or removed in freezing?
heat is removed in freezing .
What is a heat reaction?
This the heat released during a chemical reaction.

In the water cycle heat energy is released during the processes of condensation and freezing. 334 J/g is released during freezing and 2260 J/g is released during condensation.
Is Freezing a Thermal Energy Added?
No, freezing is a result of losing thermal energy (heat).
Why does salt ice melt slower than ice with no salt?
The freezing point of water is lower with added salts; the heat of solution is released.
What type of energy is used during of the process of freezing?
none. energy is lost and that is thermal
Heat is eliminated during the process of freezing this loss of heat is considered what kind of change?
This loss of heat is considered a physical change.
Is heat energy being added or removed during boiling?
added
Is heat supplied or removed in freezing?
heat is removed in freezing .
The amount of energy released by one kilogram of a substance at its freezing point?
Heat of Fusion
Is heat energy being added or removed during the process of evaporation?
In condensation heat is removed In evaporation heat is added
How can freezing and fire both be exothermic reactions?
Freezing is not a chemical reaction, it is a phase change. There is a certain amount of heat that is required to liquefy any substance, and that heat can be recovered, so in that sense, you can extract heat from the process of freezing. This is quite different from the way that heat that is released by a fire, but in some sense both are exothermic processes.
When you are making ice cream do the changes of state is a release of heat or an absorption of heat?
Freezing is an exothermic phenomenon; the enthalpy of fsion is released.
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
