Ch 19: OAE Physics: Kinetic Theory & Thermodynamics

About This Chapter

Review the material in this chapter to prepare for questions on the OAE Physics exam asking about units of temperature, heating curves, radiation, the second law of thermodynamics and the kinetic theory of matter.

OAE Physics: Kinetic Theory & Thermodynamics - Chapter Summary

Through this chapter, improve your understanding of the measurements of temperature, properties of heat and the kinetic theory. Start by watching the lesson videos taught by professional instructors, who are also available to answer any question you may have about thermodynamics. After this video series, you should have a better understanding of:

  • Conversions between Kelvins and Celsius
  • Energy diagrams
  • Phase changes of heat
  • Specific heat capacity of substances
  • Heat transfer and the Stefan-Boltzmann Law
  • Entropy and systems
  • Kinetic theory and the four states of matter
  • The ideal gas law and calculation for the properties of gases

Reinforce your understanding of the material presented in these lessons by completing the self-assessment quizzes. Take the lesson quizzes to find areas of weakness. Then, return to the areas of the lesson videos that discuss these topics using the provided links or video timeline tags.

OAE Physics: Kinetic Theory & Thermodynamics - Chapter Objectives

The OAE Physics exam is a computer-administered certification exam used to measure educators mastery of physics. On test day, you will be asked complete 150 multiple-choice questions in a 225-minute testing session. Twenty-eight percent of these questions will cover the domain of modern physics, including some questions about thermal energy and kinetic theory. Use the tools in this chapter to improve your understanding of kinetic theory and thermodynamics.

Temperature Units: Converting Between Kelvins and Celsius

1. Temperature Units: Converting Between Kelvins 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.

Changes in Heat and Energy Diagrams

2. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

Phase Changes and Heating Curves

3. Phase Changes and Heating Curves

Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.

How to Calculate Specific Heat Capacity for Different Substances

4. How to Calculate Specific Heat Capacity for Different Substances

This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.

Radiation, Heat Transfer & the Stefan-Boltzmann Law

5. Radiation, Heat Transfer & the Stefan-Boltzmann Law

After watching this lesson, you will be able to explain how radiative heat transfer works, give some real-life examples of radiation, and use the Stefan-Boltzmann Law to complete radiation calculations. A short quiz will follow.

Second Law of Thermodynamics: Entropy and Systems

6. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.

The Kinetic Theory of Matter: Definition & The Four States of Matter

7. 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.

The Ideal Gas Law and the Gas Constant

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.

Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

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.
