What Are Thermometers Made of?
Answer
A thermometer is made of a vacuum- sealed glass tube with the liquid inside being either mercury, alcohol or a hydrocarbon fluid. The liquid in the glass expands and contracts when the air inside is heated and cooled, and this changes the liquid level to indicate the relevant temperature.
1 Additional Answer
The components that make a thermometer include: a liquid such as alcohol foe or mercury for the more expensive versions and a thin hollow glass tube that is calibrated. The calibration is usually done with a range of temperatures depending on application.
