Density in the solid state is slightly less than that in its liquid state, in case of____________________?
Correct answer: B. Water
- A. Carbon dioxide
- B. Water
- C. Mercury
- D. None of these
Explanation
Water is anomalous: its solid form, ice, is less dense than liquid water because hydrogen bonding creates an open crystal structure. Carbon dioxide and mercury do not show this ordinary-density reversal under standard conditions.
