Ch 8: Chapter 8: Solutions - Holt Physical Science With Earth & Space Science

About This Chapter

The Solutions chapter of this Holt Science Spectrum - Physical Science with Earth and Space Science Textbook Companion Course helps students learn the essential lessons associated with solutions. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Solutions textbook chapter.

How It Works:

  • Identify the lessons in the Holt Solutions chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover solution topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Heterogeneous Mixture: Definition & Examples

1. Heterogeneous Mixture: Definition & Examples

You come into contact with mixtures every day. Most of the foods we eat and drink are some form of mixtures. In this lesson, you will learn about heterogeneous mixtures and the types of heterogeneous mixtures recognized by scientists.

Homogeneous Mixture: Definition & Examples

2. Homogeneous Mixture: Definition & Examples

We use many types of mixtures in everyday life. In this lesson, you will learn about a type of mixture known as a homogeneous mixture so you will be able to identify them in the future.

Solutions, Solutes, and Solvents

3. Solutions, Solutes, and Solvents

Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.

Polar Molecule: Definition & Examples

4. Polar Molecule: Definition & Examples

In this lesson, you will learn about polar molecules. A few polar molecules will be discussed to describe the process of determining polarity. Finally, a test of your knowledge will be performed.

Properties of Water

5. Properties of Water

Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.

Nonpolar Covalent Bond: Definition & Examples

6. Nonpolar Covalent Bond: Definition & Examples

When two atoms come together to share or take electrons, they do so in order to achieve a more stable, low energy state. Sometimes two atoms of the same element bond by sharing outer electrons. This is called nonpolar covalent bonding.

The Rate of Dissolution: Factors and Definition

7. The Rate of Dissolution: Factors and Definition

Learn what dissolution is and the factors that affect the rate of dissolution, such as temperature, surface area, polarity and pressure. Learn what miscible and immiscible mean in regards to liquids.

Solubility and Solubility Curves

8. Solubility and Solubility Curves

Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.

Calculating Molarity and Molality Concentration

9. Calculating Molarity and Molality Concentration

Learn the abbreviations and meaning of molarity and molality. Then apply what you have learned by going over some sample calculations with given concentrations.
