The macroscopic scale involves substances that are large enough to be visible to the human eye (without the help of optical instruments to provide a magnified view). Some important quantities that are dealt with on the macroscopic scale include:
- Melting and boiling points
- The coefficient of linear thermal expansion
- Latent heat of vaporisation
- Enthalpy of fusion
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.
