Test your knowledge with a 30-question chapter practice test
What is Temperature? - Definition & Measurement

1. 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.

Phase Changes and Heating Curves

2. Phase Changes and Heating Curves

Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

3. Mechanisms of Heat Transfer: Conduction, Convection & Radiation

There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.

Forms of Energy: Thermal, Radiant, Chemical, Electric & Nuclear Energy

4. Forms of Energy: Thermal, Radiant, Chemical, Electric & Nuclear Energy

After completing this lesson, you will be able to explain what energy is, and describe in detail thermal, radiant, chemical, electric and nuclear energy. A short quiz will follow.

The Laws of Thermodynamics

5. The Laws of Thermodynamics

Learn about the first and second laws of thermodynamics. Find out how energy is generated, how it converts from one form to another, and what happens to energy in a closed system.

First Law of Thermodynamics: Law of Conservation of Energy

6. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.

Second Law of Thermodynamics: Entropy and Systems

7. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.

Thermal Expansion: Definition, Equation & Examples

8. Thermal Expansion: Definition, Equation & Examples

In this lesson, you will learn what thermal expansion is and discover an equation for calculating how much different materials expand. You'll look at a number of examples of thermal expansion. A short quiz will follow.
