Document Summary
A law is a summary of observed behavior, it tells what happens: e. g.

Iupac international union of pure & applied chemistry. The properties of matter are determined largely by the properties of atoms and molecules they are made up of: atoms are really small, there are enormous number of atoms in any object we can see. Rules: express a number as a product of a number between 1-10 to the appropriate power of 10. If the number is 10 or greater, you must move the decimal point to the left and the appropriate power of 10 is positive.
