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).
The liquid metal in many thermometer is mercury (Hg).
Mercury (Hg) because it is the only metal which is a liquid at room temperature and conducts heat well. It also has a large range (-39 to 357 oC).However, mercury is rarely used in thermometers today, due to its toxicity. If you come across a liquid metal thermometer, it is most probably one containing an alloy of indium, gallium and tin.
where liquid Hf is used
It can hold 2 metal plates together.
When heat is applied to metal: It expands the metal Makes it hotter (Obviously) Makes it more maliable (Bendy) Can change its state to liquid at extreme temperatures.
