Solution
Correct Answer:
Thermal equilibrium
- Statement: If two thermodynamic systems A and B are each in thermal equilibrium with a third system C, then A and B are in thermal equilibrium with each other.
- Conceptual Outcome: This law provides the physical basis for the concept of temperature.
- Property: It allows us to use system C as a 'thermometer' to compare the temperature of other systems without bringing them into direct contact.
- Conclusion: The law formally defines thermal equilibrium (a state where no net heat flows between systems even if they are in contact).
This easy difficulty physics question is from the chapter thermodynamics, covering the topic of zeroth law. It appeared in the 2025 exam.
