Per NCERT §5.6(b), ENTROPY S is best described as which?
AEqual to enthalpy
BA thermodynamic state function representing the degree of disorder / randomness of the system
CAlways equal to internal energy
DA path function only
Answer & Solution
Correct answer: B. A thermodynamic state function representing the degree of disorder / randomness of the system
Per NCERT §5.6(b), entropy = measure of disorder; state function; ΔS independent of path. Crystalline solid lowest, gas highest.
