What is the Kelvin Planck statement of the second law?
The Kelvin–Planck statement (or the Heat Engine Statement) of the second law of thermodynamics states that it is impossible to devise a cyclically operating heat engine, the effect of which is to absorb energy in the form of heat from a single thermal reservoir and to deliver an equivalent amount of work.
What is the Kelvin Planck expression of the Second Law of Thermodynamics What is the Clausius expression of the second law of thermodynamics?
The Clausius statement expresses that it is impossible to build a system operating in a cycle that transfers heat from a low-temperature medium to a high-temperature medium. The Clausius inequality delivers a mathematical expression of the second law of thermodynamics: (2.17)
What is the Clausius statement of the second law of thermodynamics?
The Clausius 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 cooler body to a hotter body.
Which of the following is correct as per the second law of thermodynamics?
Therefore, it is impossible to transfer heat from a body at a lower temperature to a body at a higher temperature, without the aid of an external source according to Clausius statement of the second law of thermodynamics. Hence the correct option is (B).
What is the second law of dynamics?
The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered state.
Which one is incorrect statement of second law of thermodynamics?
It is impossible to construct an engine which will work in a complete cycle, and produce no effect except the raising of a weight and cooling of a heat reservoir.
Which one of the following is a reversible process?
Solution : Change of state and electrolysis, both are reversible, Diffusion and heat conduction are not.
Can adiabatic process be isothermal?
For an adiabatic process, in which no heat flows into or out of the gas because its container is well insulated, Q = 0. If there is also no work done, i.e. a free expansion, there is no change in internal energy. For an ideal gas, this means that the process is also isothermal.
What’s the difference between isothermal and adiabatic process?
As per the thermodynamic terminology, in the adiabatic process, there is no exchange of heat from the system to its surroundings neither during expansion nor during compression. Whereas in the isothermal process, the temperature remains constant throughout the work.
What is adiabatic process example?
Adiabatic Process Example It is a process where there is a gas compression and heat is generated. One of the simplest examples would be the release of air from a pneumatic tire. Adiabatic Efficiency is applied to devices such as nozzles, compressors, and turbines. One of the good applications of the adiabatic process.
What is the equation of adiabatic process?
For such an adiabatic process, the modulus of elasticity (Young’s modulus) can be expressed as E = γP, where γ is the ratio of specific heats at constant pressure and at constant volume (γ = CpCv ) and P is the pressure of the gas .
