Density of Mercury at Different Temperatures

The density of mercury is approximately 13,600 kg/m3 at room temperature, making it one of the densest known elements in the liquid state. The high density of mercury is a result of its relatively large atomic mass and closely packed atomic structure.

The table below lists the density values for liquid mercury at different temperatures, measured at 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
