Question:

Why does ice float in liquid water?

A) The liquid water molecules have more kinetic energy and thus support the ice.

B) The ionic bonds between the molecules in ice prevent the ice from sinking.

C) Ice always has air bubbles that keep it afloat.

D) Hydrogen bonds stabilize and keep the molecules of ice farther apart than the watermolecules of liquid water.

E) The crystalline lattice of ice causes it to be denser than liquid water.

Answer:
D) Hydrogen bonds stabilize and keep the molecules of ice farther apartthan the watermolecules of liquid water.
