Question:
Zeroth law of thermodynamics is concerned with
Zeroth law of thermodynamics is concerned with
Show Hint
Zeroth Law = Temperature. If A=C and B=C, then A=B.
Updated On: May 5, 2026
- Thermal conductivity
- Thermal diffusivity
- Thermal resistivity
- Thermal equilibrium
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
The Zeroth Law provides the basis for the definition of temperature.
Step 2: Meaning
It states that if two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other.
Step 3: Analysis
This law allows us to use thermometers to measure temperature. If the thermometer (system C) shows the same reading for system A and system B, then A and B are at the same temperature (in thermal equilibrium).
Step 4: Conclusion
The law is concerned with thermal equilibrium.
Final Answer: (D)
