About This Chapter
MEGA Chemistry: Liquids, Solids & Phase Changes - Chapter Summary
Prior to taking the MEGA Chemistry exam for teacher certification, study this chapter's lessons on liquids, solids and phase changes. Gather new information and refresh your memory of familiar topics such as:
- The kinetic molecular theory
- Phase diagrams
- Phase changes such as evaporation and freezing
- Fusion and vaporization
- Heating curves
Credentialed instructors walk you through each subject using short, engaging video lessons. The self-assessment quizzes test your knowledge, and they can be utilized as worksheets when you print them out for study purposes. The jump feature under the Timeline tab allows you to skip to the videos' main subjects.
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.
