There are several conservation laws; they were discovered and expanded gradually, over time. In modern physics, several conservation laws are derived from Nöther's Theorem. For example, the law of conservation of momentum is related to the fact that physical laws are the same in different parts of the Universe, whereas the law of conservation of energy is related to the physical laws being the same at different times. (This is basically advanced math, so I can't explain the "why", and if I could, you would probably not understand it - but if you want to try, do some reading on Noether's Theorem.)
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.
it conserves mass
[the law of conservation of energy]Wrong: The law of conservation of energy says that energycannot be created or destroyed. Do not change an answer unless you know the answer.The correct answer is the Law of Conservation of Charge, which states that the net charge of an isolated system remains constant.
The law that states energy is never created or destroyed is the First Law of Thermodynamics, also known as the Law of Conservation of Energy. This law states that energy can be transferred or transformed, but it cannot be created or destroyed.
The law is: Energy can not be created, nor destroyed.
This is the Law of Conservation of Matter.
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
Law of energy conservation. It shows that energy cannot be created or destroyed
law of conservation
The law of conservation of matter
The law of conservation of matter is also known as the law of conservation of mass. It states that mass is neither created nor destroyed in a chemical reaction, only rearranged.
