Question

For a constant volume gas thermometer one should fill the gas at (A) High temparature and high pressure (B) High temparature add low pressure (C) Low temparature and low pressure (D) Low temparature and high pressure

A real gas behaves as an ideal gas at high temperature and low pressure. So, for a constant volume gas thermometer, one should fill the gas at high temperature and low pressure for better sensitivity of temperature measurement.

Q. For a constant volume gas thermometer one should fill the gas at

High temparature and high pressure

High temparature add low pressure

Low temparature and low pressure

Low temparature and high pressure

A real gas behaves as an ideal gas at high temperature and low pressure. So, for a constant volume gas thermometer, one should fill the gas at high temperature and low pressure for better sensitivity of temperature measurement.
