Question

The variance defined by Zeroth law of thermodynamics is

• A. Temperature
• B. Internal energy
• C. Work
• D. All of these

Answer 1

Answer: (A)

Temperature

Given: Zeroth law of thermodynamics.

Solution:

1. According to zeroth law of thermodynamics,if two bodies are each in thermal equilibrium with any third body then they are in thermal equilibrium with each other.

2. When two bodies are in thermal equilibrium,it means both the bodies are at same temperature. So, the variance here is temperature.

Hence, correct option is A.
