Mercury has the lowest melting point of all metals, and it's the only liquid metal at room temperature. This fact, combined with its high density, low volatility, low wettability and high coefficient of thermal expansion make it the most popular liquid used in thermometres, barometres and manometres. Liquid mercury readily forms amalgams with many other heavy metals such as gold and silver, a property that has been used throughout history in the extraction of these metals.
