Ch 7: Phase Changes for Liquids and Solids - AP Chemistry: Homeschool Curriculum

About This Chapter

The Phase Changes for Liquids and Solids unit of this AP Chemistry Homeschool course is designed to help homeschooled students learn about general theories and definitions related to phase changes. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our AP Chemistry Homeschool course will benefit any student who is trying to learn about phase changes for liquids and solids. There is no faster or easier way to learn about chemistry. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn to describe a phase change and interpret a heating curve.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a chemistry curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and a Phase Changes for Liquids and Solids unit exam confirm understanding or identify any topics that require review.

Phase Changes for Liquids and Solids Unit Objectives:

  • Explain the processes of freezing, evaporation and condensation.
  • Learn to locate triple point and phase equilibrium boundaries by interpreting phase diagrams.
  • Understand heat vaporization and the heat of fusion.
  • Discuss the properties of solids and liquids.
  • Distinguish between phase diagrams for water and other substances.
  • Study unit cells and crystal structures.

The Kinetic Molecular Theory: Properties of Solids and Liquids

1. The Kinetic Molecular Theory: Properties of Solids and Liquids

This lesson explores the kinetic molecular theory and how it pertains to the properties of solids and liquids. You'll learn the properties of solids and liquids, discover the types of intermolecular attractions that occur between them and gain an understanding how phase changes happen.

Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries

2. Phase Diagrams: Critical Point, Triple Point and Phase Equilibrium Boundaries

Learn what a phase diagram is and how to interpret phase diagrams. Discover how to use a phase diagram to locate the phase equilibrium boundaries. Also, learn what a triple point and critical point are and how to locate them on a phase diagram.

Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

3. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.

Heat of Fusion & Heat of Vaporization: Definitions & Equations

4. Heat of Fusion & Heat of Vaporization: Definitions & Equations

When a substance changes states, like from a solid to a liquid, a lot is happening. This lesson will examine the heat of fusion and the heat of vaporization. It will also explain both formulas.

Phase Diagram of Water vs Other Substances: Differences & Meaning

5. Phase Diagram of Water vs Other Substances: Differences & Meaning

Phase diagrams give scientists specific information about how phase changes occur at different pressures and temperatures. This lesson examines phase diagrams, focusing on water and how it's a little different from most other substances.

Phase Changes and Heating Curves

6. Phase Changes and Heating Curves

Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.

Crystal Structures and the Unit Cell

7. Crystal Structures and the Unit Cell

This crystallography lesson explores the structure and properties of crystals. You'll learn about the parts of a crystal structure, types of crystals and patterns created by unit cells.
