Physical changes can include changes in size, shape, or state, while chemical changes involve the formation of new substances. Good effects of physical changes can include creating new materials like paper from wood pulp, while good effects of chemical changes include producing new medicines through chemical reactions. Both types of changes can be used to create new products and materials for various applications.

Temperature change: Significant heat or cooling effects can indicate a chemical reaction is occurring. Formation of a precipitate: When a solid substance forms in a solution, it suggests a chemical change has taken place.
The process of iron rusting is a chemical change. This is because the iron reacts with oxygen in the presence of water to produce iron oxide, a new substance with different chemical properties than the original iron.
