General Overview :: Conservation Of Mass
The law of Conservation of mass, also known as principle of Mass destroyed, although it may be rearranged in space, and changed into different types of particles. This implies that for any chemical process in a Closed system, the mass of the reactants must equal the mass of the products. As opposed to mass conservation, the principle of matter conservation may be considered as an approximate physical law, that is true only in the classical sense, without consideration of Special relativity and Quantum mechanics. Another difficulty with the idea of conservation of "matter," is that "matter" is not a well-defined word scientifically, and when particles which are considered to be "matter" are annihilated to make photons then conservation of matter does not take place, even in isolated systems. Mass is also not generally conserved in "open" systems , when various forms of Energy are allowed into, or out of, the system . However, the law of mass conservation for closed systems, as viewed over time from any single Inertial frame, continues to be true in modern Physics. The reason for this is that relativistic equations show that even "massless" particles such as photons still add mass and Energy to closed systems, allowing mass to be conserved in all processes where energy does not escape the system. In relativity, different observers may disagree as to the particular value of the mass of a given system, but each observer will agree that this value does not change over time, so long as the system is closed.
