The concept of temperature is related to:
Correct answer: A. Zeroth law of thermodynamics
- A. Zeroth law of thermodynamics
- B. Second law of thermodynamics
- C. First law of thermodynamics
- D. Third law of thermodynamics
Explanation
The Zeroth Law of Thermodynamics establishes the concept of thermal equilibrium. It states that if two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This principle provides the foundation for defining and measuring temperature.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
