About This Chapter
Ideal Gas Law & Kinetic Theory - Chapter Summary
Follow along with our expert physics instructors to review kinetic theory and the ideal gas laws. This collection of simple and entertaining lessons simplifies complex physics concepts, such as the gas constant, Dalton's law of partial pressures, ideal gas law deviations and much more. You can also learn how to use these theories and laws to solve a variety of physics problems. Each lesson comes with a short quiz, and we've included a chapter exam to help you check your understanding of the material. These resources are available at any time of day or night, and you can study on any computer or mobile device. By the end of the chapter, you should be able to:
- Summarize the kinetic theory of matter, the ideal gas law, the gas constant and Dalton's law of partial pressures
- Explain what the kinetic theory of matter says about the states of matter and the properties of gases
- Calculate pressure, volume, temperature and gas quantity using the ideal gas law
- Solve problems involving the ideal gas law
- Understand how real gases deviate from the ideal gas laws
1. The Kinetic Theory of Matter: Definition & The Four States of Matter
Everything on Earth is made of matter, but that matter isn't always the same. Matter can exist in four different phases, and the kinetic theory of matter helps us understand the differences between those phases.
2. The Kinetic Molecular Theory: Properties of Gases
What makes a gas ideal? What types of characteristics do ideal gases have? In this lesson, we will discuss the many characteristics of gases and how knowing the microscopic properties of gas particles will help you understand the macroscopic properties of a gas.
3. 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.
4. Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas
In another lesson, you learned that the ideal gas law is expressed as PV = nRT. In this video lesson, we'll go one step further, examining how to rearrange the equation to solve for a missing variable when the others are known.
5. Ideal Gas Law Problems & Solutions
The ideal gas law has four variables in it: moles, temperature, pressure, and volume. In this lesson, we will practice using the ideal gas law to calculate pressure, temperature and volume of gases.
6. 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.
7. 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.
