a law of physics that states that mass can not be created or destroyed only transferred from one volume to another
The principle that states that mass is neither created nor destroyed, merely exchanged from one form to another. Thus for any closed system, the total mass is constant, but the amount of energy in any one form may change. See also Conservation of Energy
The principle (of Newtonian mechanics) that states that mass cannot be created or destroyed but only transferred from one volume to another. In meteorology, this principle is generally expressed in the form of the equation of continuity.
The law of conservation of mass/matter, also known as Law of Mass Conservation (or the Lomonosov-Lavoisier law), states that the mass of a closed system of substances will remain constant, regardless of the processes acting inside the system. An equivalent statement is that matter changes form, but cannot be created nor destroyed. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products.
