About This Chapter
Water in Chemistry - Chapter Summary
The lessons in this chapter provide an overview of water, including its properties and significance in human biology. These lessons let you review and test your comprehension of topics like dipole-dipole and ion-dipole forces. You can also gain a clearer understanding of how to calculate the boiling point of water and the density of solids. After completing the chapter, you should be prepared to:
- Explain the properties of water
- List strengths of hydrogen bonding
- Discuss surface tension and capillary action in relationship to intermolecular forces
- Describe differences in the molecular shape of water, ammonia, and hydrogen sulfide
- Explain how to calculate the density of solids or liquids
- Compare distribution of water in the biosphere, lithosphere, hydrosphere, and atmosphere
- Recall the causes and effects of erosion
- List different types of natural resources
Each lesson comes with a brief quiz to determine how much of the content you can remember. You can study all of the lessons within this chapter or just focus on specific topics you need to review. Make the most of this resource by printing the quiz in worksheet form to study offline.
1. 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.
2. Hydrogen Bonding, Dipole-Dipole & Ion-Dipole Forces: Strong Intermolecular Forces
Learn about intermolecular vs. intramolecular forces. Learn the different intermolecular bonds (including hydrogen bonding and dipole-dipole and ion-dipole forces), their strengths, and their effects on properties, such as boiling and melting points, solubility, and evaporation.
3. Surface Tension, Capillary Action, Viscosity & Physical Changes
There are many mysteries in the universe. This lesson will focus on a few that can be easily explained due to intermolecular forces, mainly surface tension, capillary action, viscosity, and physical changes.
4. Water, Ammonia & Hydrogen Sulfide: Structures, Properties & Comparison
Typically, elements close together on the periodic table produce similar properties in the molecules, but ammonia, hydrogen sulfide, and water have very different properties. We'll learn what causes them to have such different properties in this lesson.
5. How to Calculate the Density of Solids or Liquids
After watching this video, you will be able to explain what density is and calculate the density of solids or liquids from physical measurements. A short quiz will follow.
6. How to Calculate Boiling Point
In this lesson, we look at how to calculate the boiling point of water based on a variety of factors. Altitude, air pressure, and adding substances can all affect the boiling point. A quiz is provided to check your understanding.
7. Water in Earth's Atmosphere
Water exists in three of the four states of matter on, in and around our planet. In this lesson we will look at where water is found, how much of it exists and how it is distributed.
8. The Role of Water in Human Biology
After completing this lesson, you will be able to explain why water is so important, and describe the five main functions of water in the human body. A short quiz will follow.
9. Aquatic Ecosystems & Abiotic Factors
In this lesson, you will learn what aquatic ecosystems are. You will also learn about the abiotic factors that affect them, from light levels, to flow rate, to salinity.
10. Erosion: Definition, Causes & Effects
In this lesson, we'll define erosion and discuss the causes of erosion such as wind, water, glaciers, and people. Furthermore, we'll discuss how these factors effect landforms on the earth's surface.
11. What Are Natural Resources? - Definition & Types
Natural resources are materials provided by the Earth that humans can use to make more complex (human-made) products. In this lesson, you will learn some examples of natural resources and how to classify them.
