Question

9. A digital thermometer does not use mercury.​

Answer 1

Answer:

Digital thermometers use a non-toxic alcohol instead of mercury to register the temperature.

Explanation:

Like liquid mercury, the alcohol expands in volume as it gets warmer, causing the liquid to move up the thin tube inside the glass thermometer. Digital thermometers contain a device called a thermoresistor.

There is a lot of concern over the use of mercury in thermometers. Mercury is a toxic substance and is very difficult to dispose of if a thermometer

breaks. These days digital thermometers are available which do not use mercury.
