Question

For a constant volume gas thermometer, one should fill the gas at

• A. High temperature and high pressure
• B. Low temperature and low pressure
• C. Low temperature and high pressure
• D. High temperature and low pressure

Answer 1

The correct option is D

High temperature and low pressure

A real gas behaves as an ideal gas at high temperature and low pressure. So, for better sensitivity of temperature measurement, constant volume gas thermometer should be filled with gas at high temperature and low pressure.
Final answer (c)
