The temperature of both the cavity and the particle must be the same and the temperature of the latter must not be allowed to drop in order to respect the zeroth law. Under this condition, full equilibrium between the walls and the particle would exist and the cavity could easily be demonstrated to contain black radiation [15].
And, while most memorable in their reiteration thirty-five years later in Robots and Empire, both the "Zeroth Law" and the logic that compels villainous supercomputer V.I.K.I.
The total energy of each system does not change and the zeroth law is not violated.
There is no violation of the first law and the zeroth law guarantees the equilibrium arguments.
