This refers to the law of conservation of mass. It is generally used when balancing chemical reactions as it states that the total mass of the substances undergoing a chemical reaction is always the same: before, during, and after the chemical reaction. The "closed system" part means that no matter is gained from the surrounding environment nor lost to it.
Keep in mind though that this law isn't valid for nuclear reactions, in which the total mass of the system does vary. In any case, you can always use the law of conservation of energy, as matter itself is a form of energy (see the famous equation E=mc2).
Mass in a closed system will not change. In a truly closed system, where there is no external exchange of energy, neither will pressure.
The mass remains the same as described by the law of conservation of mass/matter.
It is a closed system.
This is the law of mass conservation. If the external surface of the container react with air the law is not applicable, a new compound is formed.
The metal will rust over time but the mass of the container as a whole. The law of conservation of mass is not violated.
According to the Law of Conservation of Mass, matter can neither be created nor destroyed, only change forms. Therefore, if you burn magnesium inside of a closed container, the mass will remain the same. ---- However you will get heavier ash than you had magnesium as the Oxygen in the air in your container will be transfered. But Total Mass is 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.
In a chemical reaction, the total mass of the reactants is always equal to the total mass of the products.
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
This is the law of mass conservation. If the external surface of the container react with air the law is not applicable, a new compound is formed.
The metal will rust over time but the mass of the container as a whole. The law of conservation of mass is not violated.

But Total Mass is conserved.
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.
Conservation of mass. It means that in a closed system, the amount of mass doesn't change over time.
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 mass of reactants is equal to the mass of products.
It doesnt. Law of Conservation of Mass.
This is a general law of nature - the law of mass conservation.
