As a substance reaches its boiling point it changes from a liquid to a gas. As this happens the bonds that are holding the molecules together break allowing the molecules to wander off on their own as a gas. 6. As a substance reaches its freezing point it turns from a liquid to a solid.
What happens to substances or materials that undergo physical and chemical changes? That depends on which change. Physical changes may result in a change in appearance, but never a change in composition. Ripping, folding, melting, boiling, dissolving, and câ¦rumpling are examples of physical changes. After all of these, the substance is still made of the same atoms/elements. A chemical change will change both the appearance and composition of the matter. Examples of this are burning and reacting with acid.
