What is Thermal Energy? - Definition & Examples

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.

How Fuel Becomes Heat Energy

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.

Modeling Changes in State: Heat & Energy

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.

Autotrophs and Heterotrophs

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.

Heat Flow in Solids & Fluids

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.

Transferring Heat Energy by Radiation

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.
