Helium gas
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.
The gas thermometer was invented by Joseph Louis Gay-Lussac, a French chemist and physicist, in the early 19th century. Gay-Lussac's work on gas laws and temperature measurements laid the foundation for modern thermometry.
The silver-colored liquid inside a thermometer is typically mercury, which is a heavy metal that expands and contracts with changes in temperature, allowing the thermometer to measure and display the temperature accurately.
The colored substance commonly used in a thermometer is typically either dyed alcohol or a non-toxic organic liquid like mercury. These substances expand and contract with changes in temperature, allowing the thermometer to measure temperature variations.
Thermometer holder is a tool to hold the thermometer for taking the different reading of the body,liquid, or mass. So this holder helps to hold the thermometer,this holder is made up of such material(cork) so it does not effect the temperature of thermometer.
Beacause it is easily available
Helium is typically used in making a volume gas thermometer due to its low boiling point, inertness, and the fact that it remains a gas at very low temperatures. Additionally, helium has a very low thermal conductivity, which helps in isolating the gas in the thermometer from its surroundings.
The range of a gas thermometer depends on the type of gas used. Common gases used in gas thermometers have ranges from very low temperatures up to high temperatures, typically ranging from close to absolute zero to a few thousand degrees Celsius.
A constant volume thermometer measures temperature by keeping the volume of the gas inside the thermometer constant. As temperature changes, the pressure of the gas inside the thermometer also changes, which can be correlated to the temperature. This type of thermometer is commonly used in laboratories and for precision measurements.
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.
No, for a standard constant-volume gas thermometer, the choice of gas does not significantly affect the thermometer's performance. The key factor is that the gas behaves ideally, following the ideal gas law, which relates pressure, temperature, and volume. This allows for accurate temperature measurements regardless of the specific gas used.
The principle of a gas thermometer is based on the relationship between the volume of gas and its temperature. As the gas temperature increases, its volume expands proportionally. By measuring this volume change, the temperature of the gas inside the thermometer can be determined.

the thermometer that works on constant pressure
Constant gas thermometers are preferred over constant volume thermometers because the gas thermometer can be easily adjusted to atmospheric pressure, providing accurate readings. Additionally, the gas thermometer can measure a wide range of temperatures, making it versatile for various applications. Constant volume thermometers are limited in the range of temperatures they can measure and are less commonly used for precision measurements.
Celsius
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.
