Question

Assertion (A) : There is a natural asymmetry between converting work to heat and converting heat of work.
Reason (R ) : No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion into work.
A. If both (A) and (R ) are correct, and (R ) is the correct explanation for (A).
B. If the both (A) and (R ) are correct, but(R ) is not a correct explanation for (A).
C. If (A) is correct, but (R ) is incorrect.
D. If both (A) and (R ) are incorrect.

Answer 1

(A) is true, (R ) is true, (A) is the correct explanation for (R ).
There is a natural asymmetry between converting work to heat and converting heat to work. No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion into work. this is in accordance with the second law of thermodynamics.
