Zeroth Law of Thermodynamics:
The Zeroth Law of Thermodynamics is one of the fundamental principles in thermodynamics. It states that when two systems are in thermal equilibrium with a third system, they are also in thermal equilibrium with each other. This law helps establish the concept of temperature and allows for the measurement and comparison of temperatures.

Explanation of the Correct Answer (Option D):
The correct answer, option D, states that when two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This means that if two systems A and B are individually in thermal equilibrium with a third system C, then they are also in thermal equilibrium with each other. In other words, the temperatures of systems A and B are equal when they are both in thermal equilibrium with system C.

Explanation of the Other Options:
Let's discuss why the other options are incorrect:

a) Two thermodynamic systems are always in thermal equilibrium with each other:
This statement is incorrect because two systems may or may not be in thermal equilibrium with each other. The Zeroth Law states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. However, it does not guarantee that all systems are always in thermal equilibrium with each other.

b) If two systems are in thermal equilibrium, then the third system will also be in thermal equilibrium:
This statement is incorrect because the Zeroth Law does not suggest that if two systems are in thermal equilibrium, the third system will also be in thermal equilibrium. The Zeroth Law only establishes the relationship between two systems that are individually in thermal equilibrium with a third system.

c) Two systems not in thermal equilibrium with a third system are also not in thermal equilibrium with each other:
This statement is incorrect because the Zeroth Law does not provide any information about the relationship between two systems that are not in thermal equilibrium with a third system. It only addresses the relationship between systems that are in thermal equilibrium with a common third system.

Conclusion:
In conclusion, the Zeroth Law of Thermodynamics states that when two systems are in thermal equilibrium with a third system, they are also in thermal equilibrium with each other. This law helps establish the concept of temperature and is fundamental in understanding and analyzing thermodynamic systems.
