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.
conservation of matter, (in physics) a law stating that matter can be neither created nor destroyed and that the amount of matter in the universe is finite. It is superseded by the special relativity equation e = mc 2, but it is still applicable in the chemical process.Also called conservation of mass.onservation of matter, (in physics) a law stating that matter can be neither created nor destroyed and that the amount of matter in the universe is finite.
