- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about phase changes in liquids and solids
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Phase Changes in Liquids and Solids chapter exam.

Students will review:
This chapter helps students review the concepts in the chemical phase change unit of a standard high school chemistry course. Topics covered include:
- Characteristics of liquids and solids
- Different types of phase changes
- Heat of fusion and evaporation
- Phase diagrams
- Types of unit cells and crystal structures
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.
