What is the conservation of matter?
Flexi Says:
Though matter can change states, and it often does, matter cannot be created or destroyed. Similar to the law of the conservation of energy, the law of conservation of mass states that the mass (or matter) of an isolated system will remain constant over time. This means that mass or matter cannot be created or destroyed, although it may be rearranged and changed into different types of substances. Hence, matter is continuously recycled, resulting in the so called "circle of life." The carbon and other elements of organisms are recycled to be used by other living organisms. This law also states that in a chemical reaction, or a biochemical reaction, as mass cannot be created or destroyed, the mass of the reactants must equal the mass of the products. In other words, the atoms in the starting materials must be equivalent to the atoms in the ending materials.
