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.

How is the gas thermometer made in physic?
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.
What is a constant volume gas thermometer?
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.
How does a volume gas thermometer owrk?
Gases expand or contract when heated or cooled. The main part of the thermometer has a 'large' bulb containing a gas connected by a hose to a tube filled with liquid. The expansion or contraction of the gas causes the liquid level to move this indicates the temperature.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
What liquids other than mercury and alcohol are used in a 6s thermometer?
gas from your mom

Can i use liquid crystal thermometer to measure level of gas in a cylinder?
A thermometer is not adequate in this situation.
What is the mortality and morbidity rate of thermometer use?
Injuries caused by properly inserted and normally functioning thermometers are extremely rare.
Define vapor pressure thermometer?
A thermometer which utilizes a gas(vapor) to react to temperature changes for an accurate reading. (Instead of a hazardous material such as a mercury filled thermometer.)
