The Constant Volume Gas Thermometer
The constant volume gas thermometer is a device used to measure the temperature of a gas at a constant volume. It works on the principle that at low pressure, the temperature of the gas is proportional to its pressure at constant volume.
Pressure-Temperature Relationship
According to Gay-Lussac's law, the pressure of a gas is directly proportional to its temperature when the volume is kept constant. This means that if the temperature of a gas is increased, its pressure will also increase. Similarly, if the temperature of a gas is decreased, its pressure will also decrease.
The Relationship in the Constant Volume Gas Thermometer
In the constant volume gas thermometer, the volume of the gas is kept constant. Therefore, according to Gay-Lussac's law, the pressure of the gas will be directly proportional to its temperature. This allows the thermometer to measure the temperature of the gas by measuring its pressure.
Advantages of the Constant Volume Gas Thermometer
The constant volume gas thermometer has several advantages over other types of thermometers. These include:
- High accuracy: The constant volume gas thermometer can measure temperatures with a very high degree of accuracy.
- Wide range: The constant volume gas thermometer can measure temperatures over a wide range, from very low temperatures to very high temperatures.
- No calibration needed: The constant volume gas thermometer does not need to be calibrated, as the pressure-temperature relationship is well known and does not change over time.
Conclusion
In conclusion, the constant volume gas thermometer works on the principle that at low pressure, the temperature of the gas is proportional to its pressure at constant volume. This allows the thermometer to measure the temperature of a gas with a high degree of accuracy over a wide range of temperatures.

We know that PV=mRT and it holds good at low pressure and high temperature. If volume is constant P is proportional to T (since R is constant and m depends on gas and is also constant). Therefore, at low pressure, the temperature of gas is proportional to its pressure at constant volume.
