The freezing point of mercury is -38.83 degrees Celsius (-37.89 degrees Fahrenheit). This means that mercury will transition from a liquid to a solid state at this temperature.
Mercury is unique because it remains in a liquid state at room temperature, unlike most other metals. This property makes it useful in various applications, such as thermometers and barometers. However, due to its toxicity, the use of mercury has been significantly reduced in recent years.
