Information
zeroth law of thermodynamics (Definition)
Definition 1.1   If two systems, A and B, are separately in equilibrium with a third system C, then they are also in equilibrium with one another.
Remark 1.1   The zeroth law of thermodynamics describes the transitive nature of thermal equilibrium.
Remark 1.2   Despite its apparent simplicity, the zeroth law has the consequence of implying the existence of an important state function, the empirical temperature $\Theta$, such that systems in equilibrium are at the same temperature.
