Question

is helium gas thermometer used to measure temperature of near absolute zero​

Answer 1

Answer:

A thermometer having Helium liquid can be used, but not Helium gas

Explanation:

A gas thermometer is a thermometer that measures temperature by the variation in volume or pressure of a gas.

In case of helium, the helium at very low temperature can be used due to the fact that Helium has weak interatomic forces ,hence it can retain its liquid state even close to absolute. So instead of Helium gas, its liquid state can be used in thermometers. In this case, Helium 3 and 4 isotopes are mostly used

Answer 2

Yes, helium gas thermometer is used to measure temperature of near absolute zero​.

Explanation:

• Thermometer is a instrument used to measure the temperature of the environment. The unit of the thermometer is in Kelvin.
• The absolute zero temperature refers to the lowest possible temperature of the system. At this temperature the motion of the particle becomes lowest and the machines stops functioning.
• Absolute temperature = 0 K = - 273.15 °Celsius
• The helium gas thermometer is a constant-volume thermometer, works based on the pressure.
• The range of helium gas thermometer is -270 °C to + 1500 °C.
