A Short Note On Kelvin-Planck Statement

The Kelvin–Planck statement, often known as the heat engine statement, of the second law of thermodynamics, asserts that it is impossible to design a heat engine that receives heat from the hot reservoir and transfers all of the energy into usable external loads without cooling down to the cold reservoir.

Kelvin-Planck And Clausius Statements

Heat transfer is indeed an irreversible process that takes place only in one direction. The Kelvin-Planck statement expresses the laws of thermodynamics for heating systems, whereas the Clausius statement expresses the second law of thermodynamics for refrigerators and heat pumps.

Second Law Of Kelvin, Planck, And Clausius

“It is not conceivable to construct a mechanism that functions on a cycle and results merely in the transfer of heat, doing no other work, from a cooler body to a hotter one,” Clausius writes. Assume an engine that violates the Kelvin-Planck equation.

Kelvin-Planck Equation

The Kelvin-Planck Equation: It is difficult to build a device that functions on a cycle and generates no impact other than the heat exchange from a single entity in order to generate work.

Explanation: The Kelvin-Planck hypothesis: A heat engine cannot create a network throughout a whole cycle if it simply exchanges heat with bodies at a constant fixed temperature.

The Solution In Detail

Explanation: The statement of Kelvin-Planck: “It is impossible to design a mechanism that runs on a cycle and has no other effect than the heat exchange from a single entity in order to do work,” says Kelvin-formulation Planck’s of the second law.

We know that the two types of energy are heat (Q) and work (W). Both use the SI unit Joules and are interchangeable. This indicates that work may be transformed into work and vice versa. Work can be completely changed into heat in this case, but heat cannot be completely converted into work. As a result, work is referred to as high-grade energy, whereas heat is referred to as low-grade energy.

The Kelvin-Planck statement consists of two separate assertions made by Lord Kelvin and Planck. They are known as the Kelvin and Planck statements.

According to the Kelvin statement, it is impossible to obtain mechanical action from any substance by chilling it below the greatest cooling heat objects.

According to Planck’s remark, the entire sum of enthalpies for the reversible systems remains constant.

Properties Used As Base In Kelvin-Planck Statement

The Kelvin-Planck statement was developed by combining both of these propositions.

The kelvin-Planck statement, commonly known as the heat engine statement, is a statement from the laws of thermodynamics that asserts it is impossible to create a device that runs on a cycle and has no other effect other than heat exchange from a single body for the generation of work.

Second Law Of Thermodynamics

The total entropy of a closed system (the heat amount of energy temperature that really is unavailable for just doing productive work) can never decrease, according to the second rule of thermodynamics.

The second law of thermodynamics is a fundamental thermodynamic law concerning heat and its loss during the conversion. It may be expressed in several ways, the most basic of which is that not all heat energy can be turned into work in a continuous cycle.

According to the second rule of thermodynamics, when energy transforms from one form to another and then matter flows freely in a closed system, entropy (disorder) rises. Heat, pressure, and density differences tend to balance out horizontally after a period.

Equivalence Of Kelvin Planck And Clausius Statement

The second law is identical to the Clausius and Kelvin-Planck formulations. The equivalence of the Kelvin Planck and Clausius statements may be demonstrated by proving that breaching one can result in violating the other. The Clausius and Kelvin-Planck versions of the second law are identical.

It demonstrates that perhaps the heat engine only transfers heat with a single reservoir at a particular specified temperature T2. This contradicts the Kelvin-Planck equation. As a result, if one of the statements between Kelvin-Planck and Clausius is broken, the other is likewise violated.

Second-generation perpetual motion machine (PMM2): The PMM2 is a hypothetical machine that generates a network in a full rotation by transferring the heat only with one reservoir. It contradicts the Kelvin Planck assertion.

Conclusion

We studied everything about Kelvin Planck’s statement, state’s second law of thermodynamics, the equivalence of Kelvin Planck and Clausius’s statement, and all topics related to A Short Note On Kelvin-Planck Statement.

The kelvin-Planck statement, commonly known as the heat engine statement, is a statement from the second law of thermodynamics that asserts it is impossible to create a device that runs on a cycle and has no other consequence other than heat exchange from a single body for the generation of work.
