Two examples of chemical changes are the rusting of iron and the combustion of gasoline. In chemical changes, new substances are formed due to the rearrangement of atoms.
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
Physical changes can range from colour changes to change in tempricture.
