About This Chapter
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.
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.
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.
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.
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.
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.
6. 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.
7. What is Nuclear Energy? - Definition & Examples
You've probably heard of nuclear energy. But what is it? And what is the difference between fusion and fission? This lesson will answer your questions about this exciting form of energy that involves atoms and their nuclei.
8. What is Mechanical Energy? - Definition & Examples
In physics, energy is how work gets done. This video describes one important type of energy, mechanical energy, and provides examples of both kinetic and potential mechanical energy.
9. What is Thermal Energy? - Definition & Examples
This lesson defines and identifies examples of thermal energy everywhere from your kitchen to the Earth's core. We'll discuss geothermal energy, a renewable energy source, as well.
10. What is Radiant Energy? - Definition & Examples
This lesson defines and describes radiant energy in its different forms. The different types of electromagnetic waves created by radiant energy are identified and described as well. This includes X-rays, microwaves, and radio waves, to mention a few.
11. What is Chemical Energy? - Definition & Examples
This lesson describes chemical energy as a type of potential energy stored in chemicals, such as sugar and gasoline. The lesson discusses how energy is transferred from solar energy to chemical energy by plants and how gasoline is a source of chemical energy used to move cars.
12. What is Electric Energy? - Definition, Sources & Examples
Electricity is all around us, but where exactly does it come from? In this lesson, you'll explore the most basic source of electric energy and understand how this electron movement provides something that we often take for granted in our modern lives.
13. What is Steam Energy? - Definition & Examples
Steam, a naturally occurring substance, can be used for many things. We have learned how to utilize the energy in steam for our own benefit, and in this lesson, you'll learn about what exactly steam is and where it comes from.
14. What is Solar Energy? - Definition, Pros & Cons
Learn about solar energy and how charged particles from the sun travel to Earth to provide heat and light. Explore solar energy as a direct and indirect energy source and examine the pros and cons of harvesting solar energy for other uses.
15. How to Calculate Specific Heat Capacity for Different Substances
This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.
16. 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.
