Which planet will float on water?
-
Saturn
-
Mercury
-
Pluto
-
Venus
A
Correct answer
Explanation
Saturn's average density is approximately 0.69 g/cm³, which is less than water's density of 1 g/cm³. This means Saturn would indeed float if placed in a sufficiently large body of water. The other planets mentioned (Mercury, Pluto, Venus) all have densities greater than water.
