Question

Water: A Cool Molecule in achieve 3000
Based on information in the article, which of the following best describes how molecules in ice and molecules in liquid water differ?

Molecules in ice are positively charged, while molecules in liquid water are negatively charged.
Molecules in ice have more hydrogen atoms than molecules in liquid water.
Molecules in ice have an angular shape, while molecules in liquid water have a round shape.
Molecules in ice are farther apart than molecules in liquid water.

Answer 1

Molecules in ice are farther apart than molecules in liquid water.

Ice forms an open hydrogen-bonded crystal that holds molecules at greater average distances, making ice less dense than liquid water.
