- Defining kinetic molecular theory and pressure
- Explaining how to convert between Kelvins and Celsius
- Demonstrating your knowledge of Boyle's law, Charles' law and Gay-Lussac's law
- Sharing how to use Avogadro's law to calculate the quantity or volume of a gas
- Discussing the ideal gas law and gas constant
- Analyzing real gases
Feel confident that you'll be able to succeed on the test by brushing up on your knowledge of the properties and laws of gases using the lessons in this chapter. Watch the lessons as videos, or review the text transcripts with helpful vocabulary words. Utilize timelines if you want to skip to key topics within the videos without watching them in their entirety. Each lesson offers a short quiz designed to gauge your understanding of the materials. If you have questions about any lesson topic, don't hesitate to submit them to our experts.
1. 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.
2. Pressure: Definition, Units, and Conversions
Have you ever wondered what pressure is and how it gets measured? In this lesson, we are going to define pressure and explain some of the units that are used to express measurements of pressure.
3. 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.
4. 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.
5. 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.
6. Gay-Lussac's Law: Gas Pressure and Temperature Relationship
You may know that you aren't supposed to put an aerosol can in a fire because it could explode, but do you know why? In this lesson, we will explain Gay-Lussac's law, which shows the relationship between the temperature and pressure of a gas.
7. Molar Volume: Using Avogadro's Law to Calculate the Quantity or Volume of a Gas
Have you ever wondered why a balloon expands when you blow it up? How something as light as air is able to exert a force large enough to inflate a balloon? In this lesson, you will learn about the relationship between the volume of a container filled with a gas and the number of gas particles that container holds. This relationship is known as Avogadro's Law.
8. 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.
9. 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.
10. 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.
