Ch 8: Matter & Energy

About This Chapter

The informative and somewhat entertaining video lessons in this chapter on matter and energy teach middle school students the basics of chemical bonding. The chapter utilizes short quizzes to solidify key concepts after each lesson, and the exam concluding the chapter helps students to verify that they have mastered the material.

Matter & Energy - Chapter Summary

Video lessons for this chapter solidify basic physical chemistry skills your middle school student has learned in class. These information-packed videos familiarize students with the states and properties of matter. Your student may also utilize the short, multiple-choice lesson quizzes and the chapter exam as tools to verify their mastery of the material.

Matter: Physical and Chemical Properties

1. Matter: Physical and Chemical Properties

How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.

States of Matter: Solids, Liquids, Gases & Plasma

2. States of Matter: Solids, Liquids, Gases & Plasma

Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.

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.

Common Chemical Reactions and Energy Change

4. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Changes in Heat and Energy Diagrams

5. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

6. Mechanisms of Heat Transfer: Conduction, Convection & Radiation

There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.

First Law of Thermodynamics: Law of Conservation of Energy

7. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.
