The liquid metal in many thermometer is mercury (Hg).
The liquid typically used in a Galilean thermometer is colored alcohol.
We still use colored alcohol for our liquid in everyday thermometers.
mercury
A thermometer is used to measure air temperature, or the temperature within a solid or liquid.
iodine and Mercury
Liquid is used in a thermometer because it expands and contracts uniformly with changes in temperature, allowing for accurate temperature measurements. The liquid inside the thermometer expands and rises in the capillary tube as it gets warmer, providing a visible indication of temperature.
A thermometer is most commonly used to measure the temperature of a liquid. Other methods, such as infrared thermometers or thermocouples, can also be used depending on the specific application and characteristics of the liquid.
A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
The liquid in a thermometer does not move when turned upside down because of the properties of the liquid used (usually mercury or alcohol) and the vacuum-sealed tube design of the thermometer. This design prevents the liquid from freely moving when the thermometer is inverted.
a lab thermometer did not have a constriction as compared to clinical thermometer. it have a wide range of measurement and usually contains alcohol
The liquid is an antiseptic used to sterilise it. You wouldn't want to be contaminated with any bacteria or viruses from the last person who used the thermometer, would you?
