About This Chapter
Thermal Energy - Chapter Summary
Use the practice questions and lessons in this chapter to help to reinforce your student's understanding of thermal energy concepts. Our expert instructors will explain what thermal energy is, how fuel becomes heat energy, how heat flows in solids and liquids, and how heat energy is transferred by radiation. The lessons will also discuss changes in state, as well as autotrophs and heterotrophs. Each lesson is followed by a short, multiple-choice quiz to help assess what students have retained.
Chapter Lessons and Objectives
|What is Thermal Energy? - Definition and Examples||Define and review examples of thermal energy.|
|How Fuel Becomes Heat Energy||Explore how fuel is consumed to release heat energy.|
|Modeling Changes in State: Heat and Energy||Instructors use diagrams to show how heat causes changes in state.|

|Transferring Heat Energy by Radiation||Examine how heat energy travels across space through radiation.|
1. What is Thermal Energy? - Definition & Examples
This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.
2. How Fuel Becomes Heat Energy
When we burn wood, coal, or gas, we create heat. But where did that heat come from? Learn how fuel becomes heat energy, then test your knowledge with a quiz.
3. Modeling Changes in State: Heat & Energy
Matter exists in different phases, but it can also change from one phase to another. It's not magic, it's energy! In this lesson, you'll explore how energy can change matter from one state to another and what the names of these phase changes are.
4. Autotrophs and Heterotrophs
Ever wonder where your energy comes from? What about a plant's energy? And where does it go? Learn about the flow of energy through the food chain in this lesson on autotrophs and heterotrophs.
5. Heat Flow in Solids & Fluids
Learn about heat flow in solids and fluids: discover heat flow by conduction, convection, and radiation. See if you can tell the difference in a quiz.
6. Transferring Heat Energy by Radiation
After completing this lesson, you'll be able to explain how heat transfer by radiation works, and why it is important for life on Earth. You'll also learn how radiation is produced.
