4.2 Mixture separation methods

Quick reminder...

Transition between states

  • Melting point
  • Boiling point
  • Condensation point
  • Freezing point (crystallization)

State's properties

1. Compressibility

2. ViscosityDescribes a fluid's resistance to flow

3. MiscibilityProperty that allows two substances to fully dissolve in each other at any concentration (forming a homogeneous solution).

*Diffusion is the net movement of particles from a region of higher concentration to a region of lower concentration.
