Which aspect is not true in the context of the efficiency of a Carnot cycle engine?The efficiency of a Carnot cycle engine
Consider the following statements:
1. It is the second law of thermodynamics which provides criterion as to the probability of various processes.
2. Heat and work are completely interchangeable forms of energy.
3. Work is high grade energy.
4. The complete conversion of low grade energy into high grade energy in a cycle is impossible.
Which of the above statements are correct
The four processes of the Carnot cycle are
Hence Carnot cycle consists of two reversible isothermal and two isentropic process.
Perpetual motion machine of second kind violates the
The heat engine will produce net work in a complete cycle by exchanging heat with only single reservoir thus violating the Kelvin-Piank
The efficiency of a thermodynamic cycle cannot be infinite since it
Second law of thermodynamics defines
Kelvin-plank law deals with
Kelvin-Plank gives the concept of heat engine hence, it is conversion of heat into work.
The efficiency of the Carnot cycle may be increased by
In a Carnot engine, when working substance gives heat to the sink
In Carnot engine, source and sink is thermal energy reservoir hence as heat is rejected or extracted, temperature does not change.
Which of the following represents Carnot cycle
