Water vapour is made of small H2O\text{H}_2\text{O}H2O molecules. The water vapour is cooled until it condenses. What happens to the forces and bonds during this change?
Intermolecular forces hold the molecules closer together, while the covalent bonds within each molecule stay intact.
The intermolecular forces are replaced by covalent bonds when the molecules enter the liquid state.
Both the intermolecular forces and the covalent bonds are formed as the molecules become a liquid.
The covalent bonds within each molecule become stronger, but the forces between molecules do not change.
