Question

The molecular structure of water contains two atoms of hydrogen and one atom of oxygen. When water reaches its boiling point and turns into water vapor, what happens to its molecular structure? A. It remains the same. B. It changes the ratio of atoms. C. It forms bigger molecules. D. It forms lighter molecules.

Answer 1

The chemical bonding between hydrogen and oxygen remains same even if we chage state but the intra molecular distance between molecules increases which increase volume and decrease density.
