What is Heat Energy? - Facts & Calculation

1. What is Heat Energy? - Facts & Calculation

In this lesson, you will learn about heat and that heat is a form of energy. You will learn about the properties of heat and the equations that will help you calculate heat in a variety of situations.

Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

2. Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

When you hear the term 'nuclear power,' what comes to mind? Do you know where that energy and power is coming from? In this lesson, we are going to zoom in on the nucleus of a helium atom to explain how something as small as a nucleus can produce an extremely large amount of energy.

Thermal Conductivity: Definition, Equation & Calculation

3. Thermal Conductivity: Definition, Equation & Calculation

This lesson explores and defines thermal conductivity, its equation, and how it differs depending on the material. It also gives examples of how to calculate thermal conductivity.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

4. 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.

Changes in Heat and Energy Diagrams

5. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

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.

Thermal Equilibrium: Definition, Formula & Example

7. Thermal Equilibrium: Definition, Formula & Example

In this lesson, you will learn what thermal equilibrium is, discover an equation that relates to thermal equilibrium, and go over an example of its use. A short quiz will follow.

How a System Approaches Thermal Equilibrium

8. How a System Approaches Thermal Equilibrium

After reading this lesson, you'll understand the processes that are happening at the atomic level when you turn on your heater in the winter and when you turn on your air conditioner in the summer.

Second Law of Thermodynamics: Entropy and Systems

9. 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.

Entropy: Equation & Calculations

10. Entropy: Equation & Calculations

After watching this lesson, you will be able to apply the concept of entropy to real life situations and complete calculations of entropy for a closed system. A short quiz will follow.
