Ch 9: Characteristics of Gases

About This Chapter

This overview of characteristics of gases covers topics such as gas pressure, gas volume, and temperature unit conversion. These helpful video lessons are a great resource for supplementing class materials or preparing for a test.

Characteristics of Gases - Chapter Summary

The lessons in this chapter provide an overview of characteristics of gases. You'll find an informative discussion of several scientific laws, such as the ideal gas law. After completing the chapter, you should be prepared to:

  • Discuss Graham's law of diffusion and effusion
  • Understand Boyle's law of gas pressure and volume relationship
  • Explain Dalton's law of partial pressures
  • Explore Charles' law of gas volume and temperature relationship
  • Examine the ideal gas law and the gas constant
  • Convert temperature units between kelvins and celsius
  • Describe real gases using van der Waals equation and deviation from the ideal gas laws

These video lessons are brief and engaging, which helps you to easily understand the information presented. Our expert instructors are effective and use plenty of examples. The video timelines help you navigate the videos and focus on topics that are of greatest interest to you. Each lesson has a brief multiple-choice quiz that will test your knowledge of the topics covered.

Diffusion and Effusion: Graham's Law

1. Diffusion and Effusion: Graham's Law

Have you ever been in a room where someone has put on perfume or scented lotion and a few minutes later you are able to smell it? What causes you to be able to smell something from so far away? In this lesson, we are going to use the kinetic molecular theory of gases to explain some of their behaviors and determine how we can compare the speeds of different gases.

Boyle's Law: Gas Pressure and Volume Relationship

2. Boyle's Law: Gas Pressure and Volume Relationship

Have you ever wondered how an air powered water gun works? It uses the fantastic properties of gases to make a summer day more enjoyable! In this lesson, we will be discussing Boyle's Law and the relationship between pressure and volume of a gas.

Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures

3. Dalton's Law of Partial Pressures: Calculating Partial & Total Pressures

In this lesson, you will learn how gases behave when they are mixed together and how to use Dalton's law of partial pressures to calculate partial and total pressures of gases. You will also learn how to use this information to explain how to find the partial pressure of a gas collected over water.

Charles' Law: Gas Volume and Temperature Relationship

4. Charles' Law: Gas Volume and Temperature Relationship

In this lesson, we will discover why the wind blows and what causes a hot air balloon to rise, a couple of the applications of Charles' Law that explain the relationship between the volume and temperature of a gas.

The Ideal Gas Law and the Gas Constant

5. The Ideal Gas Law and the Gas Constant

Have you ever wondered why the pressure in your car's tires is higher after you have been driving a while? In this lesson, we are going to discuss the law that governs ideal gases and is used to predict the behavior of real gases: the ideal gas law.

Temperature Units: Converting Between Kelvin and Celsius

6. Temperature Units: Converting Between Kelvin and Celsius

Have you ever wondered what the lowest possible temperature is? In this lesson, you will learn what temperature measures. You will also be introduced to the Kelvin scale (an absolute scale) and learn how it relates to the Celsius scale.

Real Gases: Using the Van der Waals Equation

7. Real Gases: Using the Van der Waals Equation

To understand real gas behavior we use the van der Waals equation. This allows us to account for the volume and attractive forces of gas molecules. In this video lesson you'll see this put into action, and understand how it is different from the ideal gas law.

Real Gases: Deviation From the Ideal Gas Laws

8. Real Gases: Deviation From the Ideal Gas Laws

The ideal gas law is used to describe the behavior of ideal gases, but sometimes the conditions are such that gases behave differently. When this is the case we can use the van der Waals equation to describe the behavior of real gases under these non-ideal conditions.
