Ch 17: Prentice Hall Chemistry Chapter 17: Thermochemistry

About This Chapter

The Thermochemistry chapter of this Prentice Hall Chemistry Companion Course helps students learn the essential lessons associated with thermochemistry. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Thermochemistry textbook chapter.

How It Works:

  • Find the lesson within this chapter that corresponds to what you're studying in the Thermochemistry chapter of your textbook.
  • Watch fun videos that cover the chemistry and scientific concepts you need to learn or review.
  • Complete the quiz after watching each video lesson to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material, or submit a question for one of our instructors.

Chapter Topics

You'll learn all of the chemistry topics covered in the textbook chapter, including:

  • Enthalpy
  • Heat of fusion
  • Heats of formation
  • Endothermic and exothermic reactions
  • Heat of vaporization
  • Calculating specific heat capacity
  • Using Hess's law to calculate change in enthalpy

Endothermic and Exothermic Reactions

1. 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.

How to Calculate Specific Heat Capacity for Different Substances

2. 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.

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.

Thermochemical Equations

4. 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.

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.
