Unit 3 · Properties of Substances and Mixtures

Chapter 3.2

Solids, Liquids, and Gases: Properties from Particles

Diamond and graphite are both pure carbon, yet one cuts glass and the other writes on paper. The difference is entirely in how the particles are held, and the same idea explains every solid, liquid, and gas.

By the end

  1. 01Predict melting point, vapor pressure, conductivity, and hardness from the type of solid
  2. 02Distinguish ionic, covalent network, molecular, and metallic solids with particle drawings
  3. 03Describe solids, liquids, and gases by how their particles move and pack
  4. 04Explain why a solid and its liquid have similar molar volumes while the gas does not
