When liquid water at 0∘C0^\circ\text{C}0∘C freezes to form ice at 0∘C0^\circ\text{C}0∘C, there are changes in the average spacing of the molecules and the overall density of the substance.
Which of the following correctly describes these changes when liquid water freezes?
The average spacing between molecules in ice is smaller than in liquid water, and the density of ice is higher than liquid water.
The average spacing between molecules in ice is smaller than in liquid water, and the density of ice is lower than liquid water.
The average spacing between molecules in ice is larger than in liquid water, and the density of ice is higher than liquid water.
The average spacing between molecules in ice is larger than in liquid water, and the density of ice is lower than liquid water.
