Laws of Thermodynamics

 Law's of Thermodynamics

Thermodynamics Laws describe the physical quantities such as Energy, Temperature, entropy that define the Thermodynamics systems at Thermodynamics equilibrium.The laws explain the relation between this quantities

There are four laws of Thermodynamics let's check it out.

1) Zeroth Law of Thermodynamics:-

Zeroth Law state that the when the two bodies are in a thermal equilibrium with the third body, Then that two bodies are in a thermal equilibrium with each other's.

2) First Law of Thermodynamics

The first law of Thermodynamics is a version of law of energy conservation

It state that the total energy of an isolated system is constant,it can be transferred from one form to another form, but can neither be created nor be destroyed.

For a Thermodynamics process without transfer of matter first law is 

Often formulated

3) Second Law of Thermodynamics:-

When two initially isolated body separate but in a nearby region,each in Thermodynamics equilibrium with itself not necessarily with each other, are then allowed to interact.Then will eventually reach a mutual Thermodynamics equilibrium.The sum of entropies of the initially isolated system is less than or equal to the final combination.

4)Third Law of Thermodynamics:-

This law indicates that as a system's temperature nears absolute zero (0 Kelvin), its entropy approaches a minimum level. In essence, it suggests that reaching absolute zero in a finite number of steps is unattainable, and at absolute zero, the system achieves a state of perfect order characterized by zero entropy.
