We can also learn about the different properties of matter, such as why a compound burns or about its ability to convert from a liquid to solid substance. Some important quantities that are dealt with on the macroscopic scale include: Considering the example of a water molecule, the macroscopic scale involves its physical state (solid, liquid, or gaseous) but does not deal with the chemistry of the H2O molecule. At this scale, the dual nature of particles is the reason that subatomic particles are sometimes referred to as waves or energy. The energy that they absorb is different for each element, kind of like a fingerprint, which can be used to identify the elements contained in a substance.
