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
Heat energy is released during exothermic processes, such as combustion, condensation, and freezing. For example, when water vapor condenses into liquid water, it releases heat to the surroundings. Similarly, when a substance changes from a gas to a liquid (like when steam turns to water) or from a liquid to a solid (like water freezing into ice), energy is released in the form of heat.
The process of evaporation in the water cycle releases energy in the form of heat. When water evaporates from oceans, lakes, or rivers, it absorbs heat energy from the surroundings to change into water vapor. This heat energy is later released when the water vapor condenses into clouds, releasing latent heat back into the atmosphere.
pChanges in bonding arrangements between atoms and molecules result in absorption or release of heat (called latent heat). For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.
heat is removed in freezing .
Endothermic reactions absorb heat from their surroundings and feel cold, whereas exothermic reactions release heat into their surroundings and can feel warm. The sensation of freezing is typically associated with endothermic processes because they absorb heat during the reaction.
Heat is released during condensation. When a gas changes to a liquid during condensation, the molecules lose energy and release it in the form of heat.

The amount of energy generated from freezing 2.5g of water can be calculated using the specific heat capacity of water and the heat of fusion for water. The energy released would be equal to the heat of fusion of water (334 J/g) multiplied by the mass of water (2.5g). By multiplying these values, you can determine the total energy released during the freezing process.
Heat of transformation is the amount of heat absorbed or released during a phase change of a substance, such as melting, freezing, vaporization, or condensation. It is the energy required to change the state of a substance without changing its temperature.
Freezing is the process where a substance changes from a liquid to a solid by extracting heat energy. So, freezing actually involves the removal of thermal energy from a substance rather than adding thermal energy.
none. energy is lost and that is thermal
The amount of heat added to the gas during the initial compression process is known as the heat of compression.

For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.
The heat that causes a substance to change form is called latent heat. This heat is absorbed or released during a phase change, such as melting, freezing, vaporization, or condensation, without causing a change in temperature.
This loss of heat is considered a physical change.
