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.

What is Energy? - Definition and Significance in Nature

4. What is Energy? - Definition and Significance in Nature

This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

5. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.

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

6. 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.

Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

7. Using the Ideal Gas Law: Calculate Pressure, Volume, Temperature, or Quantity of a Gas

In another lesson, you learned that the ideal gas law is expressed as PV = nRT. In this video lesson, we'll go one step further, examining how to rearrange the equation to solve for a missing variable when the others are known.

The Laws of Thermodynamics

8. 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.

The Zeroth Law of Thermodynamics

9. The Zeroth Law of Thermodynamics

After watching this video, you will be able to state the zeroth law of thermodynamics, what it means, and why it is important. A short quiz will follow.

Thermodynamic Processes: Isobaric, Isochoric, Isothermal & Adiabatic

10. Thermodynamic Processes: Isobaric, Isochoric, Isothermal & Adiabatic

Learn about the four thermodynamic processes and how they work: isobaric, isochoric, isothermal and adiabatic. See if you can tell the difference by taking a quiz.

Efficiency & the Carnot Cycle: Equations & Examples

11. Efficiency & the Carnot Cycle: Equations & Examples

After watching this video, you will be able to explain the Carnot Cycle, including what it represents and how it works, and calculate the efficiency of a particular Carnot engine. A short quiz will follow.
