Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances. In general a physical change is reversible using physical means.
â¢ A physical change merely changes the shape and size of the substance while a chemical change produces altogether new substance. â¢ Physical change is reversible while chemical change is irreversible. â¢ In general, physical changes are fast whereas chemical changes are slow. â¢ In a physical change only the state of matter changes while it still has the same properties. On the other hand, in a chemical change (it takes place at a molecular level) and the new substance formed has altogether different properties.
