Water is an anomalous substance that expands when it transitions from a liquid to a solid. When liquid water at 0 ∘C0\ ^\circ\text{C}0 ∘C freezes to form ice at 0 ∘C0\ ^\circ\text{C}0 ∘C, how do the average spacing between the molecules and the density of ice compare to those of liquid water?
Average spacing in ice: larger than in liquid water | Density of ice: less than liquid water
Average spacing in ice: smaller than in liquid water | Density of ice: greater than liquid water
Average spacing in ice: larger than in liquid water | Density of ice: greater than liquid water
Average spacing in ice: smaller than in liquid water | Density of ice: less than liquid water
