Several explanations are:
- the thermal expansion of water is not linear relative to temperature
- water is colorless
- water cannot be used under 0 oC or over 100 oC
A solid thermometer is more useful when measuring high temperatures because it can withstand higher ranges compared to liquid thermometers. Additionally, solid thermometers are less prone to breakage and environmental factors like vibration, making them more suitable for harsh conditions.
Mercury (Atomic number 80) is still used in some thermometers.
Most thermometers used to contain mercury until it was found to be toxic.

Mercury is unique in that it is a liquid at room temperature, unlike most other metals which are solid. This property allows it to expand evenly when heated, making it ideal for use in thermometers. In addition, mercury's high density and low reactivity make it useful in silent lights, where it conducts electricity and generates light without creating noise.

The three main types of thermometers are liquid-in-glass thermometers, digital thermometers, and infrared thermometers. Liquid-in-glass thermometers use a liquid like mercury or alcohol to measure temperature, digital thermometers provide a numeric temperature reading, and infrared thermometers measure temperature from a distance using infrared technology.
Mercury is used in thermometers.
Mercury in thermometers is in a liquid state, since mercury is liquid at room temperature.
Mercury is the element commonly used in liquid-in-glass thermometers.
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.
Liquid in glass thermometers are fragile.For precise work, they need to be recalibrated frequently.
iodine and Mercury
Some thermometers use mercury, in these the liquid is silvery. Some thermometers use a red dyed alcohol solutioin.

Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.
I think that thermometers (liquid) were once filled with mercury. Xo, Smartiiz.
