When ice melts, its mass doesn't change. It just goes through a phase change and becomes water. Again, when water evaporates, it goes through a phase change and becomes water vapor. The conservation of mass is hence proved.
The conservation of Energy-Matter.
There is the law of conservation of mass, and the law of conservation of energy. All three state: (Mass/Matter/Energy) cannot be created or destroyed, simply transferred.
Scientists call this law the law of conservation of matter
It is the principle of conservation of energy.
That would be the law of conservation of mass, conservation of matter.
If by the law of conservation you mean the Law of Conservation of Matter, then it states that matter cant be created or destroyed.
If by the law of conservation you mean the Law of Conservation of Matter, then it states that matter cant be created or destroyed.
Law of conservation
The conservation of Energy-Matter.
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
The law of conservation of matter is applied to processes not to a compound.
Answer the question...
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.
You are confusing the law of conservation of matter/mass with the law of conservation of energy. The law of conservation of matter/mass states that in a closed system matter is neither created nor destroyed. During a chemical reaction matter is rearranged, it doesn't change forms (energy can change forms). The atoms in the products are the same atoms that were in the reactants.
The law of conservation of matter states that in a chemical reaction, matter is neither created nor destroyed.
This law was demonstrated experimentally.
