About This Chapter
Who's it for?
This unit of our Chemistry: High School Homeschool course will benefit any student who is trying to learn about the phase-changing process. There is no faster or easier way to learn about phase changes for liquids and solids. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about kinetic molecular theory, phase changes, heating curves, and crystal structures.
- 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:
- Discuss the kinetic molecular theory and how it explains the properties of liquids and solids.
- Demonstrate how to use phase diagrams to pinpoint the phase equilibrium boundaries, triple point, and critical point.
- Describe the phase change processes, including evaporation, condensation, freezing, melting, sublimation, and deposition.
- Explain heat of fusion and heat of vaporization.
- Discuss how and why the phase diagram of water differs from the phase diagram of other substances.
- Explain what happens during a phase change.
- Define 'heating curve.'
- Describe crystal structures and types of unit cells.
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.
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.
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.
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.
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.
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.
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.
