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.
The law of mass conservation: in a closed system the total mass remain constant, it is not dependant from chemical or physical changes.
The law of energy conservation: in a closed system the total energy remain constant.
"Conservation", in general, means that there is some quantity that won't change over time (in a closed system).
Conservation of energy means that the total amount of energy won't change over time.Similarly for conservation of mass.
Due to the equivalence of mass and energy, scientists sometimes talk about the conservation of mass-energy.
Please note that both mass and energy are always conserved; there is no such thing as "mass-to-energy conversion".
The principle of conservation of mass states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products.
No
Mass can never be created nor be destroyed
No. That would violate the Newtonian principle of Conservation of Mass.
The total mass during a chemical process in a closed system remain constant.
matter is not created or destroyed
matter is not created or destroyed
It is the principle of conservation of energy.
Because of the principle of energy conservation the lost mass must reappear as generated energy, according to Einstein's equation E = mc²
The law of conservation of mass
The amount of matter involved in a chemical reaction does not change. The total mass of the reactant must equal the total mass of the products.
