Chemical changes means the changes which are irreversible. Ex- Making curd , because whatever the spices , water we put in that, that we can't get again. And Physical changes means the changes which are reversible Ex- Melting of ice. Because if we take water in ice tray & kept in freezer than it will become ice & again we kept it out side it will become water as it was first.
