Examples of physical changes include crumpling a piece of paper, melting an ice cube, and breaking a glass bottle. Changes in physical properties do not produce new substances and are only concerned with energy and states of matter. solidliquidchange of formraw eggcooked eggpaperashiron + oxygen rustwater & saltbaseacidChemical Changes of MatterOn the other hand, a chemical change takes place at the molecular level and occurs when one or more substances are changed into new substances with different properties. Examples of chemical changes include burning a piece of paper into ashes, cooking an egg, rusting of iron, and mixing an acid with a base to produce water and salt. Chemical ReactionsChemical reactions occur every day all around you, and even within you. Chemical reactions occur in plants during photosynthesis and in the engines of automobiles.
