Energy From Fuels - Chapter Summary

The lessons in this chapter provide an overview of energy from fuels. You can review exothermic reactions and enthalpy. There are also discussions covering thermochemical equations and calorimetry. After completing the chapter, you should be prepared to:

  • Provide examples of combustion reaction
  • Explain what happens when endothermic reactions occur
  • Discuss energy transfer in physical and chemical processes
  • Calculate enthalpy change
  • Recall details about Hess's Law
  • Explain the ideal gas law and the gas constant
  • Discuss calculations related to the combustion of fuels
  • Perform heat calculations using a simple equation

Each lesson comes with a brief quiz to ascertain how much of the content you can recall. You can study all of the lessons in order or just focus on the topics you need to review. Another feature allows you to print the quiz in worksheet form and use it to study while away from your computer.

Combustion Reaction: Definition & Examples

1. Combustion Reaction: Definition & Examples

Chemical reactions occur every day. Some of them are quite useful to us. In this lesson, you will learn about chemical reactions that are known as combustion reactions.

Endothermic and Exothermic Reactions

2. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.

Enthalpy: Energy Transfer in Physical and Chemical Processes

3. Enthalpy: Energy Transfer in Physical and Chemical Processes

This video explores the relationship between chemistry and energy. We learn the general properties of energy and the concepts of temperature and heat. We will learn about energy flow and consider the enthalpy change during chemical reactions.

Enthalpy Change: Definition & Calculation

4. Enthalpy Change: Definition & Calculation

In this lesson, we will learn how much energy is in a reaction and what can drive that reaction forward. We will also learn how to calculate the efficiency of that reaction.

Using Hess's Law to Calculate the Change in Enthalpy of a Reaction

5. Using Hess's Law to Calculate the Change in Enthalpy of a Reaction

Want to make sure you don't blow yourself up during a chemical reaction? This lesson will help you avoid this by teaching you Hess's Law. This is one way to calculate the heat transferred, or enthalpy change, of a chemical reaction.

Thermochemical Equations

6. Thermochemical Equations

In this lesson we will learn about thermochemical equations and how we use them to tell what happens to energy in equations and if the reaction is endothermic or exothermic.

The Ideal Gas Law and the Gas Constant

7. 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.

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.
