Mercury (element)
Chemical element with atomic number 80
Can you transport a coin along a sea of mercury?
The density of an object determines if it will float. An object will float if it is less dense than the liquid it is placed in. Mercury is liquid at room temperature. The density of mercury is 13.56 g/cm3. The density of a penny is 7.15 g/cm3.
What is the density of mercury? What is the density of a typical coin? Is #2 less than #1? Considering #3 and the principle of flotation, will the coin float along mercury sea surface?
