Question
A system X is neither in thermal equilibrium with Y nor with Z. The systems Y and Z
Options
must be in thermal equilibrium
cannot be in thermal equilibrium
may be in thermal equilibrium
Advertisements
Solution
may be in thermal equilibrium
The given data in the question is insufficient to specify the relation between the physical conditions of systems Y and Z. As system X is not in thermal equilibrium with Y and Z, systems Y and Z may be at the same temperature or they may or may not be in thermal equilibrium with each other. So, the only possible option is (c).
