Mercury expands and despands due to temperature. As the temperature gets higher the mercury expands, resulting in filling up to the higher temperature. Opposite for getting cooler.

Mercury is the only metal that is a liquid at room temperature, and is therefore the only metal that can be considered for a thermometer.
Metals in general expand more than most other materials when heated, which makes it easier to see the differences with the naked eye.
These two characteristics combined is the reason why mercury is suitable for thermometers.

actually, it is very uncommon to find mercury in thermometers now adays because it is toxic. most thermometers are filled with a type of alcohol. if it is silver inside, then it is an old fashioned mercury thermometer. any other color but silver, and it is an alcohol based thermometer.

Mercury is a fluid. Any type of fluid can be used to make a thermometer but mercury is the densest fluid in existence which makes it ideal for use in thermometers as it enables the thermometer to be as small as possible.

well only two thongs have found to work in thermometers mercury being one and non inflammable and alcohol which is inflammable and when the temperature gets too high they do explode.
so the mercury one is used as it works better at high temperatures.

In the old days, people used mercury to make hats. Scientists today believe that air particles are made of tiny hats, the more hats in the air, the more compressed the hats. Thus creating a higher temperature.
