The atomic heat capacities of all solid elements ______________ with decrease in temperature?
Correct answer: A. Decreases
- A. Decreases
- B. Increases
- C. Remains unchanged
- D. Approach zero at 0°C
Explanation
The heat capacity of a solid generally falls as temperature decreases because fewer lattice vibrational modes are excited. It approaches zero only near absolute zero, not at 0°C, so the general choice is decreases.
