Mercury but sinks in water​

Answer 1

Explanation:

Mercury is a metallic element and has a density of 13.5 grams per cubic centimeter (0.49 pounds per cubic inch). This means that the density of mercury is approximately 13 times greater than that of water. Therefore, some objects that sink in water will float on mercury, including pieces of lead, silver and steel.
