It is very impossible to form a device that operates on a cycle and whose effect is the heat transfer from a body which was cooler to a hotter one.There is a different way to explain the Second law of thermodynamics.

Clausius statement is one of the best way to explain the second law of thermodynamics.In this article we will discuss about the clausius statement, Clausius theorem, Second Law of Thermodynamics and its application

Clausius Statement

By the 2^nd law of thermodynamics Clausius statement states that –

“It is impossible to create a device that operates on a cycle and has no other consequences than to transfer the heat from a cooler body( low Temperature) to a hotter body (High Temperature).”

Clausius showed that when some quantity of heat q is introduced to a system at the absolute temperature T, then the system would undergo a process and that the ratio Q/T is the same for all reversible processes. He calculated the value which is given as (dS = Q/T) here, S as the entropy.

Who was Rudolf Clausius

The full name of Rudolf Clausius is Rudolf Julius Emanuel Clausius. Rudolf Clausius was a physicist and German mathematician who was responsible for the development of thermodynamics and the Clausius assertion.

He found a lot of ideas about heat and energy and how heat and properties work, which is a restatement of the Carnot cycle.

Kelvin Planck Statement

“When we give some amount of heat to a system then a system cannot provide the same amount of work output as it receives from a high-temperature reservoir”.

While a system that converts the amount of work into heat is possible, a device that converts heat back into work is not viable.

Thermal efficiency cannot be 100% with a heat engine, on the other hand.

Second Law of Thermodynamics

The second law of thermodynamics deals with the transfer of heat naturally from a hot body to a cold body.

Without the addition of energy the heat energy cannot transfer from a body at a lower temperature to a body at a higher temperature.

The First Law of Thermodynamics states that energy can neither be created nor be destroyed it can transfer from one body to another

The total amount of energy available to be used by all things in the universe remains conserved. The 2^nd Law of Thermodynamics is related to the nature of energy and how heat and energy can be transformed.

Application of Second Law of Thermodynamics

It states that heat always moves from a body at high temperature to a body at low temperature.

Refrigerators and heat pumps are work on the second law of thermodynamics which is based on the Reversed Carnot cycle
