Why is liquid to solid exothermic? Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat is released. The energy released upon freezing, known as the enthalpy of fusion, is a latent heat, and is exactly the same as the energy required to melt the same amount of the solid.
Is going from liquid to solid endothermic or exothermic? All phase changes are accompanied by changes in the energy of a system. Changes from a more-ordered state to a less-ordered state (such as a liquid to a gas) are endothermic. Changes from a less-ordered state to a more-ordered state (such as a liquid to a solid) are always exothermic.
What makes freezing liquid to solid an exothermic process? When the water is placed in a freezer, the water slowly loses heat to the surrounding cold air. The water molecules on losing energy begin to move slowly, come closer and pack close enough to change to ice. In this process, the water releases heat to the surroundings, so it is an exothermic process.
What causes them to change from liquid to solid? The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. As a result, its particles slow down and come closer together. Attractive forces begin to trap particles, and the crystals of a solid begin to form.
