Ch 21: HiSET: Energy & Heat

About This Chapter

Several different kinds of energy are covered in this chapter in addition to heat topics. Learn about this subject matter through engaging and quick video lessons to get ready for the HiSET Science subtest.

HiSET Science: Energy & Heat - Chapter Summary

Watch lessons on the laws of thermodynamics, physics, energy types and states of matter as part of your prep for the HiSET Science subtest. You'll be set to answer questions about the following energy and heat topics:

  • Calculating specific heat capacity for different substances
  • Electric, steam and solar energy
  • The kinetic theory of matter
  • Nuclear, thermal and radiant energy
  • Mechanical energy
  • The first and second laws of thermodynamics

This chapter's information-packed videos provide clear and concise definitions for all the kinds of energy along with effective examples and illustrations. The practice quizzes spanning the chapter's lessons give you helpful feedback on your grasp of the information.

Objectives of the HiSET Science: Energy & Heat Chapter

The HiSET Science test has only questions that are in multiple-choice format, the same type as the questions in the Energy & Heat chapter's self-assessment quizzes. The 50 total questions on the exam cover three areas: life sciences sciences, physical science and Earth science. Heat and energy are asked about in the physical science section, which makes up 29% of the exam's questions. You'll be given 80 minutes to complete the exam.

16 Lessons in Chapter 21: HiSET: Energy & Heat
What is Physics? - Definition, History & Branches

1. What is Physics? - Definition, History & Branches

Known as the fundamental science, physics creates a foundation for other natural sciences. In this lesson, you'll be introduced to the field of physics, learning about its history and its modern branches of study.

What is Energy? - Definition and Significance in Nature

2. 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

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.

The Kinetic Theory of Matter: Definition & The Four States of Matter

4. The Kinetic Theory of Matter: Definition & The Four States of Matter

Everything on Earth is made of matter, but that matter isn't always the same. Matter can exist in four different phases, and the kinetic theory of matter helps us understand the differences between those phases.

First Law of Thermodynamics: Law of Conservation of Energy
