physical changes are the changes..in which can be reversed and no new substance is formed...whereas the chemical changes are the changes in which a new substance is formed and that can't be reversed..

the. change in which no new substance is formed is called physical change.the change in which a new substance is formed is called chemical change.

physical change is a change in which the molecules of a substance remains same . Chemical change is a change in which substance Change into new substance
