Ch 3: WEST Chemistry: Liquids & Solids

About This Chapter

When studying for the WEST-E: Chemistry exam, use this chapter to improve your understanding of the properties of solids and liquids, phases changes, fusion and vaporization.

WEST Chemistry: Liquids & Solids - Chapter Summary

The lessons of this chapter have been put together to help you improve your understanding of the properties of solids and liquids, as well as the types and properties of phase changes. In these lessons, our expert instructors will help you study for exam questions about:

  • Kinetic molecular theory and the properties of solids and liquids
  • Processes of evaporation, condensation, freezing, melting, sublimation & deposition
  • Critical point, triple point and phase equilibrium boundaries of phase diagrams
  • Heating curves and phase changes
  • Equations for the heat of fusion and heat of vaporization
  • Comparing phase diagrams of water to other substances

After each lesson, test your understanding of the information presented in it, and discover the topics you didn't master. To improve your understanding of these topics, use the video tags to return to and review the parts of the lesson that explain them. After you have completed your review of all of the lessons in this chapter, take the practice chapter exam to test your overall understanding of the material presented.

WEST Chemistry: Liquids & Solids Objectives

Aspiring chemistry teachers take the Washington Education Skill Tests - Endorsements (WEST-E): Chemistry exam to earn their chemistry endorsement from the state of Washington. This computer-based certification exam is composed of 110 multiple-choice questions that are administered in a two-hour and 30-minute testing session. Of these questions, 26% will assess your understanding of energy and chemical bonding, and may include some questions about the phases of matter and the properties of the different phases.

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

2. 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.

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

3. 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 Changes and Heating Curves

4. 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.

Heat of Fusion & Heat of Vaporization: Definitions & Equations

5. 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

6. 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.
