Characteristics of Matter - Chapter Summary

This chapter can help you boost your comprehension of the characteristics of matter, so you're able to excel in your science coursework. Lessons examine states of matter, phase change, energy change and more. Review them in any sequence from your computer, smartphone or tablet. When you're ready to test your knowledge, take short lesson quizzes and a chapter exam. In no time, you could understand the following:

  • How to determine the mass number and atomic number of an atom
  • Ways to identify the properties and types of states of matter
  • Processes of melting, freezing, evaporation and condensation
  • Types of chemical reactions and ways energy can change when matter is conserved
  • Definition of a nuclear reaction and how it is different from a chemical reaction

5 Lessons in Chapter 3: Characteristics of Matter
Atomic Number and Mass Number

1. Atomic Number and Mass Number

Atoms are the basic building blocks of everything around you. In order to really understand how atoms combine to form molecules, it's necessary to be familiar with their structure. In this lesson, we'll dissect atoms so we can see just what really goes into those little building blocks of matter.

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.
