Solution
(iii) There is no hydrogen bonding in the frozen state of water.
(iv) Frozen water is heavier than liquid water.
Explanation:
The presence of extensive hydrogen bonding between water molecules gives it remarkable features in the condensed phase (liquid and solid phases). In comparison to \[\ce{H2S}\] and \[\ce{H2Se}\], this results in a high freezing point, high boiling point, high heat of vaporisation, and high heat of fusion.
