IN YOUR OWN WORDS means just that - your teacher wants YOU to explain it in the sort of words you use in normal speech.
It means:
* The amount of mass in a closed system - one in which no mass gets in or out - doesn't change over time.
* You might also say that mass can't be created or destroyed.
All changes, other than some nuclear reactions, must obey the Law of Conservation of Mass. Chemical reactions, physical changes, heating, cooling, and phase changes must obey the Law of Conservation of Mass.
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.
If you consider mass and energy to be equivalent and interchangeable, it does not conflict with the law of conservation of energy. E=mc2 states that energy is mass and mass is energy, so it does not disprove the law of conservation of energy.
law of conservation of mass
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
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 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.
Law of Conservation of mass(atomic mass). As mass can be considered relative to energy, therefore Law of Conservation is also correct but Law of conservation of mass is is much more accurate because here mass is a much more accurate term that is required here. Here, since, we are balancing molecules, then we require atomic or molecular mass.
it is the same as the law of conservation of mass
The Law of conservation of Energy applies to mass as mass is a form of energy, E=mc2.
Law of Conservation of Mass (aka Law of Conservation of Matter)
the law of conservation of mass
This is a general law of nature - the law of mass conservation.
it conserves mass
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
The Law of Conservation of Mass is the concept that mass cannot be created or destroyed, it simply changes form.
