Ch 2: Fundamentals of Matter

About This Chapter

This chapter focuses on elemental topics of matter. You'll review key properties, chemical processes and terms through engaging lessons that allow you to move through the material at your own pace.

Fundamentals of Matter - Chapter Summary

This chapter examines fundamental concepts within the study of matter. You'll learn about the different forms of matter as well as chemical transitions, reactions and related properties. These lessons include practice quizzes you can use to make sure you've processed each topic correctly before moving on. And once you're through the chapter, you can test your overall understanding by taking a practice final exam. These lessons can help you study the following:

  • The physical and chemical makeup of matter
  • Distinguishing between the types and properties of each form of matter
  • What goes into the processes of evaporation, condensation, freezing and melting
  • How matter is conserved and how energy changes
  • Differentiating between nuclear and chemical reactions
  • The effects of endothermic and exothermic reactions

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.

Nuclear Reaction: Definition & Examples

5. Nuclear Reaction: Definition & Examples

Learn the differences between a nuclear reaction and a chemical reaction. Also learn how the nuclear reaction involves subatomic particles including protons and neutrons. Discover the different types of nuclear reactions including fission and fusion and also how a nuclear power plant works to produce energy.

Endothermic and Exothermic Reactions

6. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
