Web12 sep. 2024 · Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions.Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > … Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat and pressure are released. This is often seen as counter-intuitive, since the temperature of the material does not rise during freezing, except if the liquid were supercooled. But this can be understood since heat must be continually removed from the freezing liquid or the freezing process will stop. The energy released upon freezing is a latent heat, and is known as the enthal…
