Ch 4: What Is Matter? - Help and Review

About This Chapter

The What is Matter chapter of this High School Chemistry Help and Review course is the simplest way to master chemistry. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of matter in chemistry.

Who's it for?

Anyone who needs help learning or mastering high school chemistry material will benefit from taking this course. There is no faster or easier way to learn chemistry. Among those who would benefit are:

  • Students who have fallen behind in understanding the properties of matter and the changes that occur in chemical matter
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about chemical matter
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Matter chapter exam.

Why it works:

*Study Efficiently: Skip what you know, review what you don't.

*Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.

*Be Ready on Test Day: Use the Matter chapter exam to be prepared.

*Get Extra Support: Ask our subject-matter experts any question about chemical matter. They're here to help!

*Study With Flexibility: Watch videos on any web-ready device.

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.

Examples of Intensive & Extensive Properties of Matter

2. Examples of Intensive & Extensive Properties of Matter

This lesson will explore some examples of intensive and extensive properties to help you identify them more easily in the future. At the end of this lesson, you should be able to define intensive and extensive properties and provide examples.

States of Matter and Chemical Versus Physical Changes to Matter

3. States of Matter and Chemical Versus Physical Changes to Matter

The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.

Chromatography, Distillation and Filtration: Methods of Separating Mixtures

4. Chromatography, Distillation and Filtration: Methods of Separating Mixtures

What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.

Beer's Law: Absorbance & Concentration

5. Beer's Law: Absorbance & Concentration

Beer's Law relates the absorbency of a substance to its chemical concentration. In this lesson, we'll review light transmittance and absorbance and how Beer's Law is used to determine chemical concentrations.

What is a Particle? - Definition & Theory

6. What is a Particle? - Definition & Theory

Particles are fundamental entities that are used by scientists to explain different types of phenomena. Learn more about them, subsequently testing your knowledge with a quiz.

Ductility: Definition & Examples

7. Ductility: Definition & Examples

What does a piece of gum, a shiny piece of gold, and aluminum wire all have in common? They are ductile materials. To understand how these are all related continue reading to learn about ductility, its definition, and examples.

Glycerol: Properties, Formula & Uses

8. Glycerol: Properties, Formula & Uses

Have you ever wondered what chemical compounds make up soap and other personal care products? If we look at the product labels on some of them, one of the ingredients is a compound called glycerol. In this lesson we will learn more about glycerol.
