  1. Intermolecular Force - Wikipedia - Covers all four major IMF types (London dispersion, dipole-dipole, hydrogen bonding, ion-dipole), their origins, relative strengths, and effects on physical properties such as boiling point and solubility.

  2. Ideal Gas Law - Wikipedia - Explains the derivation and use of PV = nRT, the relationship to Boyle's, Charles's, and Avogadro's laws, values of the gas constant R, and the assumptions underlying ideal gas behavior.

  3. Van der Waals Equation - Wikipedia - Describes the corrections for molecular volume (b) and intermolecular attractions (a) that account for real gas deviations from ideality, including the physical meaning of the Van der Waals constants.

Chemistry: The Central Science (14th ed.) - Brown, LeMay, Bursten, Murphy, Woodward - Pearson - Chapters 10 (Gases: gas laws, KMT, real gases, Van der Waals equation) and 11 (Liquids and Intermolecular Forces: IMF types, surface tension, viscosity, capillary action, crystalline vs. amorphous solids) directly align with this chapter's full content arc.

  5. Chemistry: The Molecular Nature of Matter and Change (9th ed.) - Silberberg & Amateis - McGraw-Hill - Chapters 12 (Intermolecular Forces: Liquids, Solids, and Phase Changes) and 5 (Gases and the Kinetic-Molecular Theory) provide rigorous treatment of IMF ranking, compressibility factor, and Dalton's Law with worked AP-style problems.
