Two systems, A and B, are separately in thermal equilibrium with system C. What does the Zeroth Law of Thermodynamics predict about systems A and B?
- A and B will have different temperatures as they equilibrate with each other.
- Heat will spontaneously flow from A to B, or from B to A, until equilibrium is reached.
- The total energy of A plus B will equal the energy of C.
- A and B are also in thermal equilibrium with each other. (correct)
