Explanation:
Detailed explanation-1: -Cooling a liquid decreases the speed of the molecules. A decrease in the speed of the molecules allows the attractions between molecules to bring them a little closer together.
Detailed explanation-2: -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.
Detailed explanation-3: -Cooling a solid decreases the motion of the atoms. A decrease in the motion of the atoms allows the attractions between atoms to bring them a little close together.
