Which best explains why an iceberg floats? water expands and becomes denser when it freezes. water contracts and becomes denser when it freezes. water expands and becomes less dense when it freezes. water contracts and becomes less dense when it freezes.?

Option (c) is the correct answer.

Explanation:

Density is defined as mass per unit volume.

Mathematically,       density =

When water expands then it means, volume of water increases and density of water decreases.

Since density is inversely proportional to volume, therefore, when density decreases then volume will increase and vise-versa. This means ice will float as it has less density.

Thus, we can conclude that the statement water expands and becomes less dense when it freezes best explains why an iceberg floats.
