Platinum resistance thermometer is the international standard for temperature measurement between __________________?
Correct answer: C. Both A. and B.
- A. Triple point of hydrogen and freezing point of antimony
- B. 13.81°K to 903.9°K
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
The standard platinum resistance thermometer range extends from the triple point of hydrogen, 13.81 K, to the freezing point of antimony, about 903.9 K. Thus both descriptions identify the same standard range.
