Conservation of Matter Lab
Background and Purpose:
“Antoine Lavoisier’s discovery of the Law of Conservation of Mass led to many new findings in the 19th century” (Conservation of Mass). The Law of the Conservation of Mass/Matter states that the mass of the system must remain constant over time. This is most clearly shown through chemical reactions and changes. “When large energy transfers between systems are involved, the difference between thermodynamically closed and isolated systems becomes important, since conservation of mass is strictly and perfectly upheld only for so-called isolated systems, i.e. those completely isolated from all exchanges with the environment.” (Conservation of Mass).
Matter cannot be destroyed or created by a chemical change. (Mess)
This very important principle is known as the Law of the Conservation of Matter. This law applies to ordinary chemical reactions unless it’s a nuclear reaction where matter may be changed to energy. During a chemical change, the atoms of one or more substances go under some rearrangements. The result of these rearrangements is the formation of new different substances. (Davis)
