Answer: Option (b) is the correct answer.
Explanation:
Vapor refers to the conversion of liquid state of a substance into gaseous state or conversion of a solid state into gaseous state.
Density of ice (solid state of water) is less than the density of liquid state of water. This is because there are spaces present in the crystal lattice of ice due to which it has less mass.
As a result, it has low density and hence, it floats on the surface of water.
Thus, we can conclude that the statement Solid water (ice), unlike most substances, is denser than its liquid form (water), is false.
