The true statement amongst the following is : (1) S is a function of temperature but ΔS is not a function of temperature. (2) Both ΔS and S are functions of temperature. (3) S is not a function of temperature but ΔS is a function of temperature. (4) Both S and ΔS are not functions of temperature.
- (1)
- (2)
- (3)
- (4)
Correct answer: (1)
Solution
Entropy (S) is indeed a state function that depends on temperature, while the change in entropy (ΔS) is also a function of the initial and final states, which can vary with temperature. However, ΔS itself is not defined solely as a function of temperature, making option (1) the correct statement.
