Assertion: The zeroth law said that, when two systems and are in thermal equilibrium, there must be a physical quantity that has the same value for both.
Reason: The physical quantity, which is same for both the systems, is temperature.
Reason: The physical quantity, which is same for both the systems, is temperature.
View answer and explanation
Correct option: A
If both assertion and reason are true and reason is the correct explanation of assertion
Option A (If both assertion and reason are true and reason is the correct explanation of assertion) is correct because the zeroth law defines thermal equilibrium, and temperature is the physical quantity that is the same for systems in thermal equilibrium.
