LIQUIDS and SOLIDS (and PHASE CHANGES)
**CHAPTER OBJECTIVES:
Liquids and Solids
What properties do they have in common? How do they differ?
What role does strength of particle attraction play on viscosity, surface tension, and capillary action?
Classifying Solids
Phase Changes
Equilibrium
Be able to define and describe
Heating Curves (Warming/Cooling Curves)
Vapor Pressure Graphs
Le Chatlier’s Principle
Be able to predict how a system in equilibrium will respond to an applied stress (will the system shift to make more product
(shift left)? or shift to make more reactant (shift right)?)

Classifying Solids
- Compare and contrast crystalline and amorphous solids
- Be able to classify a given substance as a network covalent network solid, metallic solid, covalent molecular solid, or ionic solid
- Know general characteristics of these four classes of solids
Phase Changes
- Know the six different phase changes, which are endothermic and exothermic
- Names as well as what phases are involved!
Equilibrium
Be able to define and describe
Heating Curves (Warming/Cooling Curves)
- Be able to read a heating curve and identify where phase changes occur
- Answer questions regarding heating curves and perform heat calculations
- Calculate the amount of heat being absorbed (or given off) as a substance is heated (or cooled)
Vapor Pressure Graphs
- Define “vapor pressure”
- Read vapor pressure curves (graphs)
- Determine the “normal boiling point” of a substance based on standard pressure
Le Chatlier’s Principle
Be able to predict how a system in equilibrium will respond to an applied stress (will the system shift to make more product
(shift left)? or shift to make more reactant (shift right)?)
