The Zeroth Law of Thermodynamics
... This tells us that subsystem A and subsystem C were also in thermal equilibrium. This is always observed to be true. It does not matter what the nature of the systems are or the manner in which they are interrogated. So, Zeroth Law of Thermodynamics If A is in thermal equilibrium with B, and B is in ...
