Unit Objectives Describe the processes represented by typical heating and cooling curves, and compute heat flows and enthalpy changes accompanying these processes Explain the construction and use of a typical phase diagram Use phase diagrams to identify stable phases at given temperatures and pressures, and to describe phase transitions resulting from changes in these properties Describe the supercritical fluid phase of matter Describe the effects of temperature and pressure on solubility State Henry’s law and use it in calculations involving the solubility of a gas in a liquid Explain the degrees of solubility possible for liquid-liquid solutions Define the concentration units of mass percentage, volume percentage, mass-volume percentage, parts-per-million (ppm), and parts-per-billion (ppb) Perform computations relating a solution’s concentration and its components’ volumes and/or masses using these units\ Express concentrations of solution components using mole fraction and molality Describe the effect of solute concentration on various solution properties (vapor pressure, boiling point, freezing point, and osmotic pressure) Perform calculations using the mathematical equations that describe these various colligative effects 3.7.0: Heating Curves and Phase Changes 3.7.0.0: Heating Curves and Phase Changes (Problems) 3.7.1: Solubility and Intermolecular Forces 3.7.1.0: Solubility and Intermolecular Forces (Problems) 3.7.2: Concentrations of Solutions 3.7.2.0: Concentrations of Solutions (Problems)
