The law of conservation of mass (sometimes referred to as the principle of mass conservation) is as follows: for any system closed to all transfers of matter and energy (both of which have mass), the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed.
The conservation of mass is a fundamental concept of physics along with the conservation of energy and the conservation of momentum. Within some problem domain, the amount of mass remains constant--mass is neither created nor destroyed.
