Ch 2: Kinetic Energy & Heat Transfer

About This Chapter

Gain a better understanding of kinetic energy and heat transfer with this overview that includes activation energy, calorimetry experiments, and more. These concise lessons are a useful resource for individuals preparing for an exam or catching up on missed class time.

Kinetic Energy & Heat Transfer - Chapter Summary

This chapter includes lessons on kinetic energy and heat transfer. You will go over free energy, heat transfer through convection, and the measurement of temperature. You will also review where activated complex fits into an activation energy diagram. After completing the chapter, you should feel confident and ready to:

  • Provide examples of kinetic energy
  • Discuss activation energy and catalysts
  • Explain how catalysts speed up chemical reactions
  • Differentiate between closed and open physical systems
  • Discuss the use of calorimetry to measure heat transfer
  • Analyze the results of calorimetry experiments
  • Identify both intended and unintended consequences of energy conservation
  • Explain how to reduce the consequences of energy conversion

Each lesson found in this chapter on kinetic energy and heat transfer is concise and you can focus on the topics that you need to review. A brief quiz is available for each lesson to test your knowledge of concepts covered, and you can also print the quizzes for use as worksheets.

Kinetic Energy: Examples & Definition

1. Kinetic Energy: Examples & Definition

To knock down a set of bowling pins, what must be true about the bowling ball? It must be moving! This lesson discusses the energy perspective of this simple truth: kinetic energy.

Activation Energy and Catalysts

2. Activation Energy and Catalysts

Learn how to define activation energy and how it relates to a reaction's energy. Learn what an activated complex is and where it fits into an activation energy diagram. Discover how a catalyst works to change the activation energy of a reaction and what this means to metabolism in the body.

Effect of Catalysts on Rates of Reaction

3. Effect of Catalysts on Rates of Reaction

In this video lesson, we will learn how catalysts speed up chemical reactions. We'll also discuss how catalysts are used in industry and consider the catalysts in our own bodies. A short quiz will test your new knowledge.

Closed & Open Systems: Definition & Examples

4. Closed & Open Systems: Definition & Examples

In this lesson, you'll learn the difference between closed and open physical systems. Explore examples of when each kind of system occurs, and learn why scientists sometimes choose one over the other.

Free Energy: Predicting the Spontaneity of a Reaction

5. Free Energy: Predicting the Spontaneity of a Reaction

Ever heard the phrase 'pushing Jell-O uphill on a hot day'? This describes a hopeless task. In this lesson, we will predict hopeful and hopeless reactions. Or put scientifically, predicting spontaneous (hopeful) and non-spontaneous (hopeless) reactions.

Heat Transfer Through Convection: Natural vs. Forced

6. Heat Transfer Through Convection: Natural vs. Forced

After watching this lesson, you will be able to explain what convection is, both natural and forced, give some examples of convection, and complete some basic calculations. A short quiz will follow.

What is Temperature? - Definition & Measurement

7. What is Temperature? - Definition & Measurement

In the most intuitive terms, temperature refers to how hot or cold something is. Learn more about temperature as a measure of the average kinetic energy of the particles in an object and test your knowledge with quiz questions.

Calorimetry: Measuring Heat Transfer and Heat Capacity

8. Calorimetry: Measuring Heat Transfer and Heat Capacity

This video lesson explains the technique of calorimetry used to measure heat transfer in chemical reactions. You will see how different materials have different specific heat capacities. You will learn how to carry out heat calculations using a simple equation.

Analyzing the Results of Calorimetry Experiments

9. Analyzing the Results of Calorimetry Experiments

In this lesson we will learn about calorimeters and how they measure the energy of a compound. We will also learn how to use the data from a calorimeter to determine the enthalpy of the reaction.

Coffee Cup Calorimetry Lab

10. Coffee Cup Calorimetry Lab

In this lab, we'll be studying properties of heat. By looking at heat transfer between a metal and water we will be able to identify a property of the metal called specific heat.

Consequences of Energy Conservation

11. Consequences of Energy Conservation

In this lesson, you will learn about the consequences of energy conservation efforts. Many of the intended and unintended consequences will be discussed.
