Question

Solid water is more dense than liquid water.
True
False

Answer 1

Water has unique property in its solid structure.

Generally all solid have high density and more compact arrangement due to strong intermolecular forces.

But water molecules are have intermolecular H-bonding and due to which they form special arrangement in them. The arrangement leads to formation of cage structure in which there is space remain in the solid. So the ice or solid water has less density than liquid water. We can also see ice floats on liquid water.

By using this argument we can say that the given statement is false.
