Law of conservation of mass.
Mass CAN be converted into energy
The word that best describes the statement that mass is neither made nor destroyed by chemical reactions or physical changes is "law".
A scientific law is a statement that describes a natural or physical phenomenon that is always true under specific conditions. In this case, the law being referred to is the Law of Conservation of Mass. According to this law, the total mass of a closed system remains constant before and after a chemical reaction or physical change. This means that mass cannot be created or destroyed, but it can be rearranged or transformed.
To determine the best choice, we need to understand the meaning of the other terms as well:
- An experiment is a scientific procedure performed to test a hypothesis or theory. It involves observations and measurements to gather empirical evidence.
- A theory is a well-tested and widely accepted explanation of a natural phenomenon that is supported by a large body of evidence.
- A hypothesis is a proposed explanation for a specific observation or phenomenon that is yet to be tested or verified.
Considering the definitions of these terms, "experiment" and "theory" don't accurately describe the statement about mass conservation. While experiments can be used to study the phenomenon and theories can be developed to explain it, the specific statement in question goes beyond the scope of experiment or theory. On the other hand, a law is a fitting description for a principle that consistently holds true, as is the case with the Law of Conservation of Mass. Therefore, "law" is the best choice to describe the statement.
