This is the law of conservation of mass.
Mass is equivalent to energy. Neither can be destroyed or created, only changed from one form to another.
Law of Conservation of Mass: mass can not be created or destroyed, it can only be changed (transformed).
The mass of the two substances before the reaction is equal to the mass of the new substance after the reaction. This is in accordance with the law of conservation of mass, which states that matter can neither be created nor destroyed in a chemical reaction, only rearranged.
During fission, a small amount of mass is changed into energy according to Einstein's equation E=mc^2. This means that a small portion of the mass of the fissionable material is converted into a significant amount of energy.
The United States is not a continent because it is only a portion of a big land, where Canada and Mexico inhabit the same land mass. Australia is a continent because it is its own place, and it owns the entire land mass. Since the United States does not own the entire land mass it is situated on, where Canada and Mexico inhabit the land mass, also, the United States is not a continent. The United States is only a country.
The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products. This means that no mass is gained or lost during a chemical reaction, only rearranged.
Momentum, and the total of mass/energy, can never be created or destroyed, only moved around.
i think that it is a law The first law of thermodynamics. Meaning, "...that energy can not be created or destroyed, it can only be changed from one form to another or transferred from one body to another, but the total amount of energy remains constant (the same)."
5 if you mean Massachusetts but only 3 if you mean states of matter
The law of conservation of mass, also known as the law of conservation of mass-energy, is based on the experiments of Antoine Lavoisier. This law states that mass or matter cannot be created or destroyed in a chemical reaction, only changed from one form to another.
Maine (from Mass) and West Virginia (from Virginia during the CW).
Actually no, the only thing that changes is the density. The mass doesn't change when it's changing states.
