Mercury!
Mercury is the element commonly used in liquid-in-glass thermometers.
Mercury is a liquid metal used in thermometers. However, it becomes a solid at -37.9 F and it can cause mercury poisoning if ingested or inhaled. Therefore, most theremometers use ethyl-alcohol or a plastic strip covered with liquid crystals (called a liquid crystal thermometer).

Many thermometers use the liquid metal mercury, Hg.
Mercury is the metal element traditionally used in thermometers due to its ability to expand and contract uniformly with changes in temperature. However, due to its toxicity, mercury thermometers are being phased out in favor of digital alternatives.
Mercury (Atomic number 80) is still used in some thermometers.
Mercury is the only metal that is liquid at room temperature. It is used in thermometers, barometers, and some electrical switches and relays.
We still use colored alcohol for our liquid in everyday thermometers.
Some times red coloured liquid is used but mostly gray coloured liquid is used.
The liquid metal used in thermometers that expands and contracts as temperature changes is mercury. Mercury is commonly used due to its unique properties, such as its wide liquid temperature range and high thermal conductivity, making it ideal for accurate temperature measurement.
