Abstract
As already said, the state quantities are the quantities chosen by the scientist or the engineer to describe a phenomenon he wants to predict. The state quantities define the equilibrium: when the state quantities remain constant with respect to the time, the phenomenon is at an equilibrium. The notion of equilibrium is subjective and depends on the sophistication of the modelling, i.e., on the choice of the state variables.
