Unit 6 Phases of Matter Review

Water molecules have a low vapor pressure because

• it has strong temporary dipole (dispersion) forces acting between its molecules
• it has strong hydrogen bonds acting between its molecules
• it has a weaker force of attraction between its molecules
• it is very volatile

The lower the boiling point, the ___ the intermolecular forces.

• stronger
• weaker
