Question

No process is possible whose sole result is the transfer of heat from a colder object to a hotter object. This is Clausius statement for

• A. Zeroth law of thermodynamics
• B. First law of thermodynamics
• C. second law of thermodynamics
• D. Carnot's theorem
• E. principle of refrigeration

Answer 1

The Correct Option is C

The Clausius statement is a formulation of the Second law of thermodynamics, which states that it is impossible for heat to flow spontaneously from a colder body to a hotter body. This principle implies that heat naturally flows from hot to cold objects, and any process that violates this is impossible. Hence, the correct statement is the Second law of thermodynamics.

The correct option is (C) : second law of thermodynamics

Answer 2

The given statement is:  

"No process is possible whose sole result is the transfer of heat from a colder object to a hotter object." 

This is known as the Clausius statement of the second law of thermodynamics. 

It implies that heat cannot spontaneously flow from a colder body to a hotter body without external work being done. 

Correct answer: second law of thermodynamics
