Learning Objectives
WHAT YOU SHOULD BE ABLE TO DO WHEN YOU HAVE FINISHED THIS TOPIC:
- Compare/contrast the qualitative properties of three states of matter: solid, liquid, gas
- Know the two factors that determine the physical state of matter.
- Know how average kinetic energy of the particles changes with temperature.
- Know the types and relative strengths of attractive forces between particles.
- Relate the physical properties of substances to the attractive forces between particles:
- For solids: melting point, malleability, ductility, conductivity, solubility in water
- For liquids: boiling point, surface tension, viscosity, vapor pressure, solubility in water
- Know the four types of solids (molecular, ionic, metallic, network covalent) and categorize individual substances based on their physical behavior.
- Sketch and interpret a typical phase diagram for a pure substance, including identification of the triple point and the critical point.
- Construct a Born-Haber diagram given appropriate energy values, and calculate any of the individual energy values where appropriate.
- 13: Condensed States and Intermolecular Forces
- The physical properties of a substance depends upon its physical state. Water vapor, liquid water and ice all have the same chemical properties, but their physical properties are considerably different. In general Covalent bonds determine: molecular shape, bond energies, chemical properties, while intermolecular forces (non-covalent bonds) influence the physical properties of liquids and solids.
