What is example of Kelvin-Planck statement?
The Kelvin-Planck statement is: “it is impossible for any device that operates in a cycle to receive heat from a single reservoir and produce a net amount of work.” Another common statement is the Clausius statement: “It is impossible to construct a device that operates in a cycle and produces no effect other than the …
What does Kelvin-Planck statement?
The Kelvin-Planck Statement: It is impossible to construct a device which operates on a cycle and produces no other effect than the transfer of heat from a single body in order to produce work.
What is Kelvin-Planck statement Class 11?
The kelvin-Planck statement, also known as the heat engine statement from the second law of thermodynamics, states that it is impossible to design a device that works on a cycle and produces no other effect other than heat transfer from a single body for the production of work.
What is Clausius statement with example?
It is impossible for heat to move by itself from a lower temperature reservoir to a higher temperature reservoir. That is, heat transfer can only occur spontaneously in the direction of temperature decrease. For example, we cannot construct a refrigerator that operates without any work input.
What is Kelvin Planck statement and Clausius statement?
The Clausius Statement was expressed as “Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time”, and the Kelvin–Planck Statement as “It is impossible to construct a device that operates in a cycle and produces no other effect than the production of …
Which of the following devices works on the Kelvin Planck?
Consider a hypothetical device known as Perpetual motion machine of the second kind (PMMSK). Furthermore, Wilhelm Ostwald introduced this device and it would perform work by absorbing energy from a body as heat. This way Wilhelm Ostwald has Kelvin-Planck Statement explained.
What is Kelvin-Planck statement and Clausius statement?
How can we violate Kelvin-Planck statement?
Since there is no heat interaction with the low temperature, it can be eliminated. The combined system of the heat engine and heat pump acts then like a heat engine exchanging heat with a single reservoir, which is the violation of the Kelvin-Planck statement.
What is Clausius law?
Clausius Statement from the second law of thermodynamics states that: “It is impossible to design a device which works on a cycle and produce no other effect other than heat transfer from a cold body to a hot body.” That is, heat transfer can only occur spontaneously in the direction of temperature decrease.
What is the relation between Kelvin-Planck and Clausius statement Mcq?
Considering relation between Kelvin-Planck and Clausius statement, if one statement between the two is violated then. Explanation : Kelvin-Planck and Clausius statements look different but both are are the parallel statements of second law of thermodynamics.
Which of the following is the Kelvin-Planck statement Mcq?
Explanation: Kelvin-Planck’s statement: According to Kelvin-Planck’s statement of the second law, “it is impossible to construct a device which operates on a cycle and produces no other effect than the transfer of heat from a single body in order to produce work.”
What is the proofs of Kelvin-Planck statement?
Kelvin-Planck Statement: – It is impossible to devise a cyclically operating device, which produces no other effect than the extraction of heat from a single thermal reservoir and delivers an equivalent amount of work. Heat engine with single thermal reservoir is not possible.
What is Kelvin-Planck and Clausius statement of second law of thermodynamics?
Which of the following exists in a PV diagram for water?
Which of the following exists in a p-V diagram for water? Explanation: The p-V diagram for water has all these three lines. 6. The triple point is a line on the p-V diagram, where all the three phases, solid, liquid and gas exist.
How Kelvin-Planck and Clausius statements are interrelated to each other in second law of thermodynamics?
Which of the following exists in a P-V diagram for?
How is triple point represented in P-V diagram?
It has been found that on a ‘p-T’ diagram the triple point is represented by a point and on a ‘p-v’ diagram it is a line, and on a ‘u-v’ diagram it is a triangle. In the case of ordinary water, the triple point is at a pressure of 4.58 mm Hg and a temperature of 0.01°C.
Which of the following can not be plotted on PV diagram?
Irreversible processes cannot be plotted in a PV diagram, because these processes cannot have unique values of pressure, the temperature at every stage of the process.
What is PV diagram give an example?
A pressure–volume diagram (or PV diagram, or volume–pressure loop) is used to describe corresponding changes in volume and pressure in a system. They are commonly used in thermodynamics, cardiovascular physiology, and respiratory physiology.
