Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the appearance or state of matter without changing the chemical composition. Chemical changes typically involve the breaking and forming of chemical bonds, resulting in new substances with different properties. Physical changes, on the other hand, involve changes in physical characteristics such as shape, size, phase, or state of matter without altering the chemical composition of the substance.
