The best example of the law of conservation of matter is complete combustion. If you were to burn something of known mass in a closed system, the system would have the same mass before and after combustion occurs.
Conservation of mass. It means that in a closed system, the amount of mass doesn't change over time.
This is a general law of nature - the law of mass conservation.
Law of mass conservation in chemistry: in a chemical reaction the mass of reactants is equal to the mass of products.Law of energy conservation: in a closed system the energy remain constant.
During chemical processes in a closed system the mass remain constant.
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
The total mass during a chemical process in a closed system remain constant.
It is where if nothing is let in or let out of a substance the mass will not change. For example, if you had a bottle with a substance in it and nothing passed in or out of that bottle, the mass would be the same no matter if a chemical reaction occurred inside the bottle. This makes sense, since mass is made up of atoms, and if the amount of atoms is the same then the mass won't change.
Well, the Law of Conservation of Mass a.k.a the Principle of Mass/Matter Conservation says that the mass of everything that is closed to all matter and energy will always remain constant over time. ~ You can only tell if mass or matter is conserved by determining if it has a closed system or an open system ~ Mass or matter is only conserved in a closed system because a closed system is a system that cannot exchange matter with its surroundings, so to say that mass or matter is conserved by being "trapped" and will stay constant. I hope this helped!! XD
Because energy can be converted into mass and vice versa. Thus, while the mass of a system is not conserved in a particular process, the mass and energy of a closed system is always conserved.
The law of conservation of mass, or principle of mass conservation, states that for any system closed to all transfers of matter and energy (both of which have mass), the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed.
