What is the Zeroth law say?
Zeroth law of thermodynamics: let's discuss the zeroth law of thermodynamics. It is the most fundamental law of thermodynamics. as a student, we must learn it in-depth and understand in importanceThermodynamics is a tricky subject that must be studied in chemistry, physics, engineering, and many other courses of academic study.
It has an incredible impact on the behavior of matter and energy.
Thermodynamic concepts may seem impossible to understand. If you go over the basics enough times, they start to make sense.
You can continue to learn more about the subject, as needed for your field of study or level of desired knowledge.
Laws of thermodynamics, zeroth first, second, third
We will begin our analysis with the infamous laws of thermodynamics. Just like Newton's laws of motion, there is a first, second, and third law.Later in the development of the field. New, more fundamental law was added and dubbed the zeroth law.
The zeroth law of thermodynamics deals with thermal equilibrium.
Statement of Zeroth Law
It states that heat always flows in the direction of the hot object to a colder one., which as we recall, describes a situation in which there is no net heat flow between two systems.
Zeroth law Examples
The zeroth law states that if two
systems are in thermal equilibrium with a third system, then those two
systems are also in thermal equilibrium with each other.
In other words, if A is in thermal equilibrium with B, which is in thermal equilibrium with C, then A and C are also in equilibrium.
This may seem like a trivial statement, but it is an important one because it means that two objects at the same temperature will not exhibit heat flow when they come into contact with one another. This marks temperature as the indicator of thermal equilibrium.
If two objects are in thermal equilibrium with thermometers that read the same temperature, the objects will be in thermal equilibrium with each other, which therefore allows us to gather all kinds of thermodynamic data in our laboratories.
In studying thermodynamics, we must also learn certain definitions. We will want to be able to define a system as the collection of objects.
We are examining while the surroundings represent the environment surrounding the system, which is technically the rest of the universe. Some systems allow heat to flow in and out.
These systems have diathermal walls. Some systems do not allow heat to flow in and out. These systems have adiabatic walls.
No system can be truly adiabatic, but it is a useful approximation when we do calculations involving systems that permit only negligible heat transfer. With these definitions out of the way, we can move on to the first law of thermodynamics.

Conclusion
let's conclude what we learned about zeroth law, it is the fundamental law that stats about the thermal equilibrium state.General FAQs
What is an example of Zeroth Law?
Best Examples of Zeroth Law is a Cup of tea exposed in the environment. Tea temperature will be thermal equilibrium with the ambient temperature/
What are the applications of Zeroth Law of Thermodynamics?
Zeroth Law is Applicable Everywhere where the temperature is concerned
What is the zeroth and first law of thermodynamics?
Zeroth law of thermodynamics – If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other. First law of thermodynamics – Energy can neither be created nor destroyed. It can only change forms.
