Energy is released.
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.
When a substance freezes, it releases energy as it changes from a higher-energy state (liquid) to a lower-energy state (solid). The energy is released as heat into the surroundings.
Energy is released when a chemical reaction is exothermic, meaning that the products have less energy than the reactants. Energy is absorbed in an endothermic reaction, where the products have more energy than the reactants.
Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.
When an electron gets excited, energy is absorbed to move the electron to a higher energy level. This absorbed energy gets released when the electron returns to its original energy level, emitting electromagnetic radiation such as light.

When 2 atoms combine to form a molecule, energy can be either absorbed or released, depending on the specific atoms involved and the type of bond being formed. This process can result in either an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed).
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 can be absorbed or released in a chemical or physical change, it is not destroyed or created. It simply assumes a different form.
energy is released
Breaking covalent bonds requires input of energy, not the release of energy. When covalent bonds are broken, energy is absorbed by the molecules involved in the process.
When substances change state, energy is either absorbed or released. During melting and boiling, energy is absorbed to break the intermolecular forces holding the substance together, while during freezing and condensation, energy is released as these forces are formed. This energy change is due to the breaking or forming of bonds between molecules.
Energy is released during freezing.
The difference in energy between the products and reactants of a chemical reaction determines if energy will be released or absorbed. If the products have lower energy than the reactants, energy will be released in the form of heat or light. If the products have higher energy, then energy will be absorbed.
