I CAN:
CHAPTER 12
 Explain physical equilibrium: liquid water –water vapor.
 Explain that vapor pressure depends on temperature and concentration of particles in solutions
 Explain how energy (kinetic and potential) of particles of a substances changes when heated, cooled or
changing phase
 Identify pressure as well as temperature as a determining factor for phases of matter
 Explain how temperature and kinetic energy are related
 Draw phase diagrams for water and carbon dioxide(show how sublimation occurs)
 Identify regions, phases and phase changes using a phase diagram
 Use phase diagrams to determine information such as (1) phase at a given temperature(2) boiling point
and melting point at a given pressure (3) triple point of a material
CHAPTER 13
 Compute concentration(molarity) of solutions in moles per liter
 Calculate molarity given mass and volume of solution
 Calculate mass of solute needed to create a solution of a given molarity and volume
 Identify types of solutions (solid, liquid, gaseous, aqueous)
 Define solutions as homogeneous mixtures in a single phase
 Summarize colligative properties (vapor pressure reduction, boiling point elevation, freezing point
depression and osmotic pressure
 Use graphs of solubility vs. temperature to identify a substance based on solubility at a particular
temperature.
 Use graphs to determine degree of saturation of solutions to temperature
 Develop a conceptual model for the solution process as a cause and effect relationship involving forces
of attraction between solute and solvent particles. ( a solution is insoluble because of a lack of attraction
between solute and solvent.)
 Explain solubility in terms of the nature of solute and solvent attraction, temperature and pressure(for
gases)
