Helium gas constant volume thermometer is suitable for the measurement of a temperature of ______________ °C?
Correct answer: B. < 0
- A. < 100
- B. < 0
- C. > 0
- D. > 800
Explanation
Helium gas thermometers are particularly suitable for low-temperature measurements below 0°C because helium remains useful in the cryogenic range. Hydrogen is more commonly associated with the approximately 0 to 100°C range.
