Relate the properties of a state to the energy content and particle arrangement of that state (p. 378-380). (Lab 1)
Explain forces and energy changes involved in changes of state (p. 381-384).
Contrast ionic and molecular substances in terms of their physical characteristics and the types of forces that govern their behavior (p. 385-386).
Describe dipole-dipole forces (p. 386).
Explain how a hydrogen bond is different from other dipole-dipole forces and how it is responsible for water's high boiling point (p. 387-389).
Describe London dispersion forces, and relate their strength to other types of attractions (p. 390-392)
Define the molar enthalpy of fusion and the molar enthalpy of vaporization, and identify them for a substance by using a heating curve (p. 393-394).
Describe how enthalpy and entropy of a substance relate to state (p. 395).
Predict whether a state change will take place by using Gibbs energy (p. 395).
Explain how pressure affects the entropy of a gas and affects changes between the liquid and vapor states (p. 398).
Identify systems that have multiple phases, and determine whether they are at equilibrium (p. 399-400).
Understand the role of vapor pressure in changes of state between a liquid and a gas (p. 400-401).
Calculate melting and boiling points by using enthalpy and entropy (p. 396-397). (Homework 1)
Interpret a phase diagram to identify melting points and boiling points (p. 402-404). (Homework 2) (Lab 2)
