Mercury :)
The liquid in a clinical thermometer is often mercury. But there are thermometers that use a coloured alcohol.
Mercury can be found in the labarotry or in the clinical thermometer.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
mercury and alcohol
Degrees Fahrenheit.
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.

Refrigerators typically use a bimetallic coil thermometer or a digital thermometer to monitor and display the temperature inside the unit. These thermometers are designed to withstand the cold temperatures found in refrigerators and provide an accurate reading of the internal temperature.
Celsius, Fahrenheit, and Kelvin.
