Energy is absorbed when water changes state from a solid to a liquid to a gas. This energy is used to break the bonds between water molecules during melting and vaporization. It is known as the latent heat of fusion and latent heat of vaporization, respectively.
When water freezes, thermal energy is released from the water as it changes from a liquid to a solid. This released energy is responsible for lowering the temperature of the water to its freezing point and then further to form ice.
The term is latent heat. It refers to the energy absorbed or released by a substance during a phase change, such as when water changes from a solid to a liquid (melting) or from a liquid to a gas (evaporation).
When there is a change of state, energy is transferred in the form of either heat or work. For example, when a substance changes from a solid to a liquid, energy is absorbed to break the intermolecular forces holding the solid together. Conversely, when a substance changes from a gas to a liquid, energy is released as the substance condenses.
The term is "latent heat." It represents the energy absorbed or released by a substance during a phase change, such as when water changes from a liquid to a solid or a gas.
The energy absorbed by one gram of water as it changes from its liquid phase into water vapor is known as the heat of vaporization. This energy is used to overcome the intermolecular forces holding the water molecules together in the liquid phase.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Condensation
It melts. Energy is absorbed.
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
When water freezes, thermal energy is released from the water as it changes from a liquid to a solid. This released energy is responsible for lowering the temperature of the water to its freezing point and then further to form ice.

It's absorbed, thus lowering the temperature.

cchemical change and energy change also the change of a gas to a liquid
Yes, when wax freezes, energy is released in the form of heat. This is because when a substance changes from a liquid to a solid state, its molecules slow down and release energy in the form of heat as they rearrange into a more ordered structure.
Energy isn't released; It is an 'endothermic' process. It requires energy for a gas to turn into a liquid. Example: Carbon dioxide is a gas as we encounter it in everyday life. To put this gas into a liquid (or even a solid), we must add pressure to the system. Adding pressure is a form of adding energy.
