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 law of conservation of matter is also known as the law of conservation of mass. Law of conservation of mass was given by Lavoisier in 1774. This law has been verified by repeated study of chemical changes using delicate balances to measure the mass of the reactants and products as a result of a chemical reaction.
