Ch 3: Georgia Milestones - Physical Science EOC: Energy & Heat

About This Chapter

Learn about the types of energy and how matter changes phases with our exciting lessons that prepare you for the Georgia Milestones - Physical Science EOC Assessment. The instructors bring experience and subject mastery to the lessons they've created.

Georgia Milestones - Physical Science EOC: Energy & Heat - Chapter Summary

This collection of lessons will help you study the definition of energy, energy transformation, and the relationship between kinetic and potential energy. Other lessons cover gravitational potential energy and the first law of thermodynamics. These lessons and others pertain to the portions of the Georgia Milestones - Physical Science EOC Assessment that deal with the subject of energy. Other topics you will look at in this chapter include:

  • Definition of, and equation for, heat capacity
  • Phase changes: gas, liquid, plasma and solid
  • Phase diagram of water
  • Heat transfer and heating curves
  • Conduction, convection, and radiation

Our lessons are designed to be both comprehensive and brief, allowing you to learn what you need to in a minimum of time and on your schedule. The video-timeline feature enables you to skip to the topic you need to review, and bold terms you find in written passages will encourage in-depth study. Each lesson has a quiz to help you ensure mastery of the subject.

What is Energy? - Definition and Significance in Nature

1. 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.

Energy Transformation: Definition, Types & Examples

2. Energy Transformation: Definition, Types & Examples

In this lesson, you will learn about the different kinds of energy and how these types of energy can be transformed from one form to another. You will also learn about some uses of these energy transformations in everyday life.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

3. 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.

Gravitational Potential Energy: Definition, Formula & Examples

4. Gravitational Potential Energy: Definition, Formula & Examples

In this lesson, you will learn what gravitational potential is, the equation we use to calculate it, and how to use that equation. We'll look at some real-life examples so you can see how it works. A short quiz will follow.

First Law of Thermodynamics: Law of Conservation of Energy

5. 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.

Heat Capacity: Definition & Equation

6. Heat Capacity: Definition & Equation

This lesson covers the topic of heat capacity, which is a core concept of thermodynamics. We will review the definition of heat and explore how it relates to an object's heat capacity.

Phase Changes and Heating Curves

7. 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.

Phase Diagram of Water vs Other Substances: Differences & Meaning

8. Phase Diagram of Water vs Other Substances: Differences & Meaning

Phase diagrams give scientists specific information about how phase changes occur at different pressures and temperatures. This lesson examines phase diagrams, focusing on water and how it's a little different from most other substances.

Heat Transfer & Phase Changes

9. Heat Transfer & Phase Changes

After watching this lesson, you will be able to explain what heat transfer is and describe the various phase changes that can result from heat transfer in terms of the position of the molecules. You will also be able to give the names of those phase changes. A short quiz will follow.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

10. 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.
