Nitrogen gas constant volume thermometer is suitable for measuring a temperature of _____________ °C?
Correct answer: A. > 100
- A. > 100
- B. < 0
- C. 0-100
- D. > 50
Explanation
A constant-volume nitrogen thermometer uses the pressure of nitrogen as an indication of temperature and is suitable for temperatures above the ordinary 0–100°C range. Gas thermometers are therefore useful at relatively high temperatures.
