Web29 mei 2024 · Is melting endothermic or exothermic? However, it can be used for both the melting and the solidification processes as long as you keep in mind that melting is always endothermic(so ΔH will be positive), while solidification is always exothermic (so ΔH will be negative). Is melting ice endothermic or exothermic? WebEssentially, melting is an endothermic process because energy is required to transform a solid into a liquid. Why is the melting of ice endothermic, in addition to the above? Ice melting is an endothermic reaction, as previously stated, because it necessitates heat for the reaction to occur.
