What does conservation of matter mean
1 answer
Conservation of matter, also known as the law of conservation of mass, is a fundamental principle in physics and chemistry. It states that matter cannot be created or destroyed in a chemical reaction or a physical change. In other words, the total mass of substances involved in a closed system before and after a reaction remains constant. This principle implies that the atoms in a chemical reaction are rearranged to form new compounds, but the total number of atoms of each element remains the same. Thus, mass is conserved in all chemical reactions and physical transformations.
