Second Law of Thermodynamic

Second Law of Thermodynamic

Second Law of Thermodynamic : Kevin-plank statement and Clausius statement 

Kevin-Plank’s Law 

  

It is impossible to construct an engine which while operating in a cyclic process,

will produce no effect other than transfer of heat from a single thermal reservoir

and the performance of an equivalent amount of work.

In simple terms, it is impossible to construct a heat engine with 100 per cent

efficiency.

Clausius’s Law 

It is impossible to construct a heat pump which while operating in a cyclic process,

will produce no effect other than the transference of heat from a low temperature

thermal reservoir to a high temperature thermal reservoir.
