Question

Explain Plank’s statement of second law with applications.​

Answer 1

$\huge\mathfrak {Answer:-}$

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.

Answer 2

Answer:

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.[1] This implies that it is impossible to build a heat engine that has 100% thermal efficiency.
