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.

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.
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.
It is based on the pressure of a fixed mass of gas.
A thermometer is typically used to measure the boiling point of a substance. It can accurately measure the temperature at which a liquid changes state from a liquid to a gas during the boiling process.
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.

A thermometer is not adequate in this situation.
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.
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.

Gas thermometers typically use either nitrogen or helium as the gas inside the thermometer. These gases are preferred due to their low boiling points and well-defined expansion and contraction characteristics with changes in temperature.
A gas thermometer works by measuring temperature based on the relationship between the pressure and volume of a gas. As the gas is heated or cooled, its pressure and volume change accordingly. By measuring these changes, the temperature can be determined using the ideal gas law (PV=nRT).
