Answer:

The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. or The total mass of any material system is neither increased nor diminished by reactions between the parts.

The law of conservation of energy states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. or The total energy of an isolated system remains constant irrespective of whatever internal changes may take place with energy disappearing in one form reappearing in another.

Answer:Albert Einstein introduced his famous equation E = mc2 in a 1905 journal submission titled, "On the Electrodynamics of Moving Bodies." The paper presented his theory of special relativity, based on two postulates:

Principle of Relativity: The laws of physics are the same for all inertial reference frames.

Principle of Constancy of the Speed of Light: Light always propagates through a vacuum at a definite velocity, which is independent of the state of motion of the emitting body.

The first principle simply says that the laws of physics apply equally to everyone in all situations. The second principle is the more important one. It stipulates that the speed of light in a vacuum is constant. Unlike all other forms of motion, it is not measured differently for observers in different inertial frames of reference.
