Why does ice float on liquid water?
A.Ice's hydrogen-bonded lattice is less dense
B.Ice contains air bubbles
C.Ice is warmer than liquid water
D.Liquid water is a gas
Explanation
Core Concept
Freezing locks water into an open hexagonal framework where each molecule bonds to four neighbors, holding molecules farther apart than in the liquid. The expanded lattice floats.
Correct Answer
AIce's hydrogen-bonded lattice is less dense
