Solution
Correct Answer:
Temperature
The Zeroth Law of Thermodynamics states: 'If two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other.'
- This transitivity implies the existence of a common physical property that determines whether systems are in equilibrium.
- This property is defined as Temperature. Systems in thermal equilibrium have the same temperature. The law provides the logical basis for using thermometers.
This easy difficulty physics question is from the chapter thermodynamics, covering the topic of zeroth law. It appeared in the 2025 exam.
