Question

What are the uses of mercury thermometer?​

Answer 1

Answer:

In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.

Also, it has a shiny appearance and doesn't stick to the glass surface of glass .
