The specific gravity of mercury is approximately 13.6. Specific gravity is a dimensionless unit that compares the density of a substance to the density of water. Since the density of water is 1 g/cm³, the specific gravity of mercury indicates that it is 13.6 times denser than water.
Mercury is a heavy, silvery metal that is liquid at room temperature. Its high specific gravity makes it useful in various applications, such as in thermometers and barometers, where its density allows for precise measurements.
Understanding the specific gravity of mercury is important in fields like chemistry, physics, and engineering, as it helps in calculating buoyancy, pressure, and other related properties.
