What is the law of conservation of matter?

Answer 1

Cannot Be Created or Destroyed.The law of conservation of matter states that matter is not created nor destroyed in any chemical or physical change.

however, this law doesn't apply to nuclear reactions because some matter is turned into energy.

Answer 2

The total amount of mass-energy in a closed system cannot change. Energy can change from one form to another, Mass can change from one form to another, Energy can change to Mass, or Mass can change to Energy; but the total must remain constant.

Since Mass and Energy are traditionally measured in different units, we need a units conversion equation to tell us how much of each has changed to the other to get the equations right. Einstein provided us with that from his Special Relativity:

E = Mc2

Answer 3

The Law of Conservation of Energy states that energy cannot be created or destroyed, but can change its form.

Answer 4

the law of conservation of energy means that energy cannot be created or destroyed

Answer 5

The law of conservation of matter is a principal of classical physics that matter cannot be created or destroyed in an isolated system. It is also called the law of conservation of mass.

Answer 6

Actually, it is the "law of conservation of mass". The total amount of mass in a closed system will remain constant - it will neither increase nor decrease.

Answer 7

Matter. Something like that.
