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.
Latent heat is the energy absorbed or released by a substance during a phase change without a change in temperature.
The change in energy during a dissolution process is called heat of solution. It represents the overall amount of energy absorbed or released when a solute dissolves in a solvent.
It depends. There are two types of chemical reaction int his sense. Exothermic reactions release energy and endothermic reactions absorb it.
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
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.
latent heat
Latent heat is the energy absorbed or released by a substance during a phase change without a change in temperature.
The heat energy released or absorbed during a change of state of water is called latent heat. This energy is used to break or form intermolecular bonds without changing the temperature of the substance.
The change in energy during a dissolution process is called heat of solution. It represents the overall amount of energy absorbed or released when a solute dissolves in a solvent.
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.

when a chemical change occurs, chemical bonds are broken up
The chemical potential energy stored in the matchstick is converted into thermal energy and light energy during burning. The heat released during the combustion reaction causes the matchstick to ignite and produce a flame.
Latent heat is the energy absorbed or released during a phase change, such as melting or boiling, without affecting the temperature of the substance. Sensible heat, on the other hand, is the energy absorbed or released that does cause a change in temperature.
Latent heat is the energy absorbed or released during a phase change without a change in temperature. It is classified into two types: latent heat of fusion, which is the energy involved in changing a substance from solid to liquid or vice versa, and latent heat of vaporization, which is the energy associated with changing a substance from liquid to gas or vice versa. These energy levels vary depending on the substance and the phase change involved.
