As the temperature is lowered towards the absolute zero, the value of the quantity (∂ΔF/∂T) approaches________________?
Correct answer: A. Zero
- A. Zero
- B. Unity
- C. Infinity
- D. None of these
Explanation
For Helmholtz free energy, (∂F/∂T)V = −S. As temperature approaches absolute zero, the entropy approaches zero according to the third law, so this derivative also approaches zero.
