Consider two identical glasses filled to the same exact leve

Consider two identical glasses filled to the same exact level, but one is filled with water and the other is filled with solid ice. Which of the following statements is true? a) That volume of ice has a greater density than that volume of liquid water. b) That volume of ice has more total water molecules than that volume of liquid water. c) That volume of ice has fewer total water molecules than that volume of liquid water. d) The water molecules in the ice are connected by hydrogen bonds as well as some covalent bonds. e) There are an equivalent number of water molecules in both glasses.

Solution

Answer is (C).

c) That volume of ice has fewer total water molecules than that volume of liquid water.

Because in ice water molecules have less hydrogen bonds so the compactness is less than liquid water.
