it is to take the temperature
The liquid metal used in thermometers is mercury. It is unique among metals because it remains in a liquid state at room temperature, allowing it to expand and contract uniformly with temperature changes. This property makes mercury ideal for accurate temperature measurements in traditional thermometers. However, due to its toxicity, the use of mercury in thermometers has been largely phased out in favor of safer alternatives.
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).

Mercury (Hg)
Mercury is the element commonly used in liquid-in-glass thermometers.
Mercury is the only metal that is liquid at room temperature. It is used in thermometers, barometers, and some electrical switches and relays.
