
Identify intermolecular attractions in substances, and relate these to the properties of
these substances.
Use visual representations to depict intermolecular forces in substances.
Relate intermolecular attractions in a liquid to vapor pressure, boiling point, viscosity and
surface tension.
Given a choice of several compounds, identify the compound with the highest boiling
point and justify your choice.
Classify types of crystalline solids as molecular, ionic, network covalent or metallic, and
describe properties of these solids.
Describe phase changes on a particulate level.
Describe equilibrium vapor pressure and standard enthalpy of vaporization and relate
these to the intermolecular forces of a liquid.
Relate vapor pressure of a liquid to temperature using the Clausius Clapeyron Equation.
Analyze phase diagrams and use them to predict conditions in which phases are stable,
and conditions of phase transitions.
