• No process is possible whose sole result is the absorption of heat and complete conversation into work.

$\large{\underline{\frak{Clausius \: statement:-}}}$

• No process is possible whose sole result is transfer of heat from cold body to hot body without expense of energy.
• Concept of Ideal refrigerator is ruled out without exchange of energy.
• For pitual motion of second point is not possible.
