A gas thermometer is a device that measures temperature by the variation in volume or pressure of a gas. It is made by filling a bulb with gas such that the volume of the gas in the bulb remains constant.
A constant volume gas thermometer is a thermometer that uses the variations of pressure in gas at different temperatures to measure the temperature. A liquid can then be put into tubes, and rather than measuring the distance of a small quantity, the distance between two parts of the curving tube are used to measure the temperature.
A gas thermometer measures temperature by the variation in volume or pressure of a gas.One common apparatus is a constant volume thermometer. It consists of a bulb connected by a capillary tube to a manometer. The bulb is filled with a gas such that the volume of the gas in the bulb remains constant. The volume is related to temperature by k, known as Charles's Law . The pressure of the gas in the bulb can be obtained by measuring the level difference in the two arms of the manometer. Gas thermometers are often used to calibrate other thermometers.

the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
the thermometer that works on constant pressure
A gas thermometer is a device that measures temperature by the variation in volume or pressure of a gas. It is made by filling a bulb with gas such that the volume of the gas in the bulb remains constant.
It is based on the pressure of a fixed mass of gas.
A constant volume gas thermometer is a thermometer that uses the variations of pressure in gas at different temperatures to measure the temperature. A liquid can then be put into tubes, and rather than measuring the distance of a small quantity, the distance between two parts of the curving tube are used to measure the temperature.

Increasing the temperature of a gas will increase it's pressure ONLY if the volume is held constant.
compressor work on two principles 1)reduce volume of a constant amount of gas 2)adding more gas in a constant amount of volume positive displacement compressor works on first principle it reduces the volume of gas by applying force on it but gas amount is constant in every stroke or rotation thus increasing the pressure. centrifugal compressor work on second principle it adds more amount of gas in a given constant volume thus the pressure increase.

as the pressure decreases the volume of gas increases at constant temperature
This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
the pressure and temperature are held constant. ideal gas law: Pressure * Volume = moles of gas * temperature * gas constant
