What does conservation of matter mean

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.

The conservation of matter, also known as the law of conservation of mass, is a fundamental principle in physics and chemistry. It states that in a closed system, matter cannot be created or destroyed; it can only be transformed or converted from one form to another. This means that the total mass of substances before and after a chemical or physical change remains constant.

In simpler terms, conservation of matter means that the amount of matter you start with is the same amount of matter you end up with, even if it goes through various changes or reactions. This principle is based on the idea that atoms and molecules are not created or destroyed during these processes; they are simply rearranged.
