The melting point of mercury is approximately -38.83 degrees Celsius (-37.89 degrees Fahrenheit). This unique property of mercury allows it to remain in a liquid state at room temperature, which is quite unusual for metals.
Mercury is the only metal that is liquid at standard conditions for temperature and pressure, making it distinct among elements. The low melting point is a result of the weak metallic bonds in mercury, which do not require much energy to break. As the temperature rises above this melting point, mercury transitions into a liquid, exhibiting interesting behaviors such as high surface tension and the ability to form amalgams with other metals.
