Pure Substances have a fixed composition and consistent properties throughout (e.g., elements, compounds).

Mixtures contain two or more substances physically combined. These can be:

  • Homogeneous (uniform, e.g., salt water)
  • Heterogeneous (non-uniform, e.g., sand and iron)

This simulation visualizes particle arrangements in different substances and mixtures.
