Mercury is a liquid at room temperature. When it heats up it expands, and when it cools it contracts. This is the re line that you see, and shows the temperature accurately. You usually have mercury because it is a liquid at room temperature, so it can go up and down freely.
Hope this helps :)

What devices contain mercury?
Thermometer or barometer
Which part of the thermometer contains the mercury?
The internal capillary contain mercury.
Does an instant thermometer used for cooking contain mercury?
No, most instanst thermometers used for cooking are digital and therefore don't contain mercury. There may be some older style thermometers that do contain mercury.
What type of Thermometer is most likely to contain alcohol?
A mercury-in-glass thermometer is most likely to contain alcohol. However, due to safety concerns, many modern thermometers use alcohol-based solutions or other materials instead of mercury.
What does a thermometer contain water or Mercury?
If it's a silver liquid it's mercury, if it's red it's alcohol (not water)
Do pool thermometers contain mercury?
Some pool thermometers do contain mercury, but there are alternatives available that use different substances like alcohol or digital sensors. If you are concerned about the presence of mercury in a pool thermometer, look for options that explicitly state they are mercury-free.
Is it a solid liquid or gas found in a thermometer?
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.
What is the diffrerence between digital thermometer and mercury thermometer?
A digital thermometer uses electronic sensors to measure temperature and displays the reading digitally, while a mercury thermometer uses a column of mercury to measure temperature and has a calibrated scale to indicate the temperature. Digital thermometers are often faster and more accurate than mercury thermometers, and are also safer since they do not contain mercury.
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
What is a non mercury thermometers?
A non-mercury thermometer is a thermometer that does not contain mercury as the temperature-sensing liquid. Instead, it may use alcohol, galinstan, or other materials to measure temperature. These alternatives are considered safer for environmental and health reasons compared to mercury thermometers.
What is in the laboratory thermometer?
There are many kinds of thermometer in use. Liquid in glass thermometers usually contain alcohol (dyed red or blue) or mercury (silvery coloured).
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
