Law of conservation states that during a chemical change, matter is neither created nor destroyed but it undergoes physical and chemical changes i.e., it will be converted from one form to another form.
- The measurable quantities remain same even though it converts from one form to another form
- Examples: Energy, Momentum and angular momentum with considerable and conserved quantities.
- Hence it is also state as Law of Conservation of Energy, Law of Conservation of Momentum, and Law of Conservation of Angular Momentum. This law doesn't change for the isolated system and it is exact.
