Anything that is not a nuclear reaction, basically. So water freezing, chemical reactions, salt dissolving, etc
Matter cannot be created nor destroyed. Matter, or mass, can only change form into other substances or energy.
Law of conservation of mass states that If one or more substance undergo a reaction, then the mass of reactants and the products remains same. Example:- CaO + CO2 ------------> CaCO3 Here mass of CaO is 56 amu and mass of CO2 is 44 amu, and mass of CaCO3 is 100 amu . This shows that, mass of reactants= mass of products 56 + 44= 100
The law of Conservation of Mass was invented by a French chemist Antoine-Laurent Lavoisier.

Antoine Lavoisier: Developed the Law of Conservation of Mass. We don't really know who discovered it. Hope that answered it...:)
conservation
For example the law of mass conservation.
the earth
matter can not be created or distroyed
because REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
An example of conservation of mass is simply cutting up a cookie into pieces. Even though you now have more pieces, it still has the same amount of mass (how much matter is made of the cookie) as you did when it was all in one piece. :)
The best example of the law of conservation of matter is complete combustion. If you were to burn something of known mass in a closed system, the system would have the same mass before and after combustion occurs.
the law of conservation of matter (or mass)
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.
you can change a mass of something if you take part of the product out of it
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
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.
There are several laws of conservation; please clarify which one you mean. For example, there is the law of conservation of mass, of energy, of momentum, of rotational momentum, of electrical charge, and others.
