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.

Critical Points and Phase Changes

• Critical Point: Point where liquid transitions to supercritical fluid.

• Sublimation and Melting: Direct transitions between gas and solid states.

Enthalpy Changes in Phase Transitions

• Calculating heats of vaporization and fusion throughout phase changes.

Energy In Solution Formation
