The glass thermometer is the most familiar of all thermometers because mercury and petrolate are the most common fluids in this kind of thermometer.

Explanation:

  • The accuracy of a typical glass thermometer is ±1 scale division.
  • These are available in partial immersion or total immersion types and typically have to be considerably longer to achieve the same specifications as a mercury thermometer.
  • Bimetal thermometers do not require power and  an economical option.
  • Organic liquids which are usually employed for construction of liquid in glass thermometers include toluene, ethyl alcohol and pentane.
  • Although their thermal expansion is high but they are non linear and their use is restricted for high temperatures.
  • This thermometer is a thin glass tube with a red or blue line inside.
  • These thermometers are safe to use for people over the age of 5.
  • A child younger than 5 may bite the thermometer, breaking it in their mouth.
  • Glass thermometers with galinstan may also be used to check an oral temperature.
  • A thermometer has a glass tube sealed at both ends and is partly filled with a liquid like mercury or alcohol.
  • The temperature around the thermometer's bulb heats up, and liquid rises in the glass tube.
  • When it is hot, the liquid inside the thermometer will expand and rise in the tube.
