About This Chapter
ORELA Chemistry: Gases - Chapter Summary
This chapter contains several video lessons that focus on the characteristics and properties of gases. One of the videos looks at the ways in which they can be compressed, and it examines the differences between real and ideal gases. Another video lesson explores kinetic molecular theory and the absolute zero temperature of gas. Recall the distinctions between gases, liquids and solids and discuss the applications of various gas laws as you prepare for the ORELA Chemistry examination. Watch the videos for assistance with:
- Explaining the principles of the kinetic molecular theory
- Exploring Boyle's Law and Charles' Law
- Discussing Gay-Lussac's Law and the ideal gas law
- Calculating pressure and temperature by using the ideal gas law
Experienced teachers and chemistry experts present the above topics in a conversational manner. The online video lessons are brief, and you can study them at your own pace. Review the fundamentals of gases in preparation for passing the ORELA Chemistry examination. Learn visually by watching the videos or read through the accompanying text transcripts. Test your retention when you complete the multiple-choice pop quizzes.
ORELA Chemistry: Gases - Chapter Objectives
The ORELA Chemistry examination is composed of 150 multiple-choice questions and five content domains. You must answer all of the questions within a three hour and 45 minute time frame. The information in the Matter and Atomic Structure content domain of the examination mirrors the material in this chapter's videos. Your ability to distinguish between the four states of matter will be evaluated. You'll also be expected to display a thorough understanding of gas laws and demonstrate your proficiency in solving equations that involve them.
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. 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.
3. 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.
4. 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.
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.
6. 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.
