Phases of Matter

  • Phases of Matter: Solids, liquids, and gases explained by intermolecular forces and thermal energy.

Intermolecular Forces

  • Types of Intermolecular Forces:

    1. Dispersion Forces

    2. Dipole-Dipole

    3. Hydrogen Bonding

    4. Ion-Dipole Forces

Vaporization and Vapor Pressure

  • Discusses thermal energy overcoming intermolecular forces, leading to vaporization.
