4. The intensive state, which includes only intensive
variables (variables that are independent of the size of
the system), is specified by only two variables in the
case of an equilibrium one-phase fluid system of one
substance.
5. Nonideal gases and liquids are described
mathematically by various equations of state.
6. The coexistence of phases can be described
mathematically.
7. The liquid–gas coexistence curve terminates at the
critical point, beyond which there is no distinction
between liquid and gas phases.
8. The law of corresponding states asserts that in
terms of reduced variables, all substances obey the
same equation of state.
