Question

14. Which of the following is incorrect?
[NCERT Pg. 305]
(1) If two systems A and B are in thermal
equilibrium with system C separately, then A
and B will be in thermal equilibrium
(2) Zeroth law of thermodynamics defines
temperature
(3) Temperature does not determine the direction
of flow of heat when two bodies are placed in
thermal contact
(4) Internal energy of an ideal gas depends on the
state of the system​

Answer 1

Answer:

The zeroth law of thermodynamics states that if two thermodynamic systems are each in thermal equilibrium with a third one, then they are in thermal equilibrium with each other. Accordingly, thermal equilibrium between systems is a transitive relation.
