The zeroth law of thermodynamics states that if two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other. Accordingly, thermal equilibrium between systems is a transitive relation.
It is called the "zeroth" law because it came to light after the first and second laws of thermodynamics had already been established and named, but was considered more fundamental and thus was given a lower number — zero.

Zeroth Law of Thermodynamics
The Zeroth Law of Thermodynamics is a fundamental principle in thermodynamics that deals with the concept of thermal equilibrium. It states that when two systems are each in thermal equilibrium with a third system, they are also in thermal equilibrium with each other.
Explanation:
1. Thermal Equilibrium
Thermal equilibrium refers to a state where there is no net flow of heat between two systems in contact with each other. In other words, the temperatures of the two systems are equal, and there is no temperature gradient between them. When two systems are in thermal equilibrium, they are said to be at the same temperature.
2. Statement of the Zeroth Law
The Zeroth Law of Thermodynamics provides a basis for defining temperature and establishing a reliable temperature scale. It states that if two separate systems are each in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other.
3. Significance of the Zeroth Law
The Zeroth Law of Thermodynamics allows us to establish a reference point for temperature measurement and comparison. It enables us to define a common temperature scale and determine whether two systems are in thermal equilibrium with each other.
4. Example
Let's consider three systems, A, B, and C. If system A is in thermal equilibrium with system B, and system B is in thermal equilibrium with system C, then according to the Zeroth Law, system C must also be in thermal equilibrium with system A. This establishes a transitive relationship between the systems.
For instance, if you have a glass of cold water (system A) and a cup of hot coffee (system B), and you place a thermometer in each, you will find that the temperatures of both systems are different. However, if you leave them in contact with each other for some time, heat will transfer between them until they reach a state of thermal equilibrium. At this point, the temperatures of both the water and the coffee will be the same (system C).
Conclusion
In conclusion, the Zeroth Law of Thermodynamics states that when two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This principle is fundamental in defining temperature and establishing a reliable temperature scale. It allows us to compare the temperatures of different systems and determine whether they are in thermal equilibrium or not.
