Does violating the second law of thermodynamics violate the first law?

A device that violates the Second law of thermodynamics is called a Perpetual Motion Machine of the Second kind. The first device supplies continuously energy with out receiving it. So this is a system creating energy and therefore violating the first law.

How can Clausius statement be violated?

Consider a refrigerator pumping QL heat from the low temperature reservoir at TL to the reservoir at higher temperature TH. Combined with the Kelvin-Planck violator, the arrangement is pumping QL heat from TL to TH, without any external agency. Hence it violate the Clausius statement.

What is a device that violates either law of thermodynamics?

Any device that violates the first law of thermodynamics (by creating energy) is called a perpetual-motion machine of the first kind (PMM1), and the device that violates the second law is called a perpetual-motion machine of the second kind (PMM2). Reversible and Irreversible Process.

Can the second law of thermodynamics be reversed?

The first law of thermodynamics provides the definition of the internal energy of a thermodynamic system, and expresses the law of conservation of energy. The second law is concerned with the direction of natural processes. It asserts that a natural process runs only in one sense, and is not reversible.

What is the statement of second law of thermodynamics?

The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.

How is violation of Kelvin-Planck and Clausius statement?

The combined system receives energy (QH-Qc) by heat transfer from a single reservoir, the hot reservoir, and produces an equivalent amount of work. So the combined system violates Kelvin-Planck statement. Thus the violation of the clausius statement implies the violation of Kelvin-Planck statement.

What are Kelvin-Planck and Clausius statement of Second Law of Thermodynamics?

Therefore, the heat transfer is an irreversible process that only occurs in one direction. The Kelvin-Planck statement is the statement of the second law of thermodynamics for heat engines, while the Clausius statement is the statement of the refrigerators and heat pumps.

What is the statement of Second Law of Thermodynamics?

What if entropy can be reversed?

Entropy is a measure of the randomness or disorder within a closed or isolated system, and the Second Law of Thermodynamics states that as usable energy is lost, chaos increases – and that progression towards disorder can never be reversed.
