Praxis Physics: Heat, Energy & Thermodynamics Chapter Objectives
The Praxis Physics exam is taken by teachers of various grade levels to get their certification in their respective state. Heat, energy and thermodynamics are included in the section of the same name, which takes up approximately twelve percent of the multiple-choice exam.
1. What is Heat? - Definition & Explanation
In this lesson, you will learn the definition of heat and find out how it differs from temperature. You will also explore practical applications of heat such as expansion, thermodynamics, heat transfer, specific heat, phase transitions, and heat engines.
2. 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.
3. 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.
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.
5. Endothermic and Exothermic Reactions
Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
6. Thermal Expansion: Definition, Equation & Examples
In this lesson, you will learn what thermal expansion is and discover an equation for calculating how much different materials expand. You'll look at a number of examples of thermal expansion. A short quiz will follow.
7. 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.
8. 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.
9. 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.
10. The Kinetic Molecular Theory: Properties of Gases
What makes a gas ideal? What types of characteristics do ideal gases have? In this lesson, we will discuss the many characteristics of gases and how knowing the microscopic properties of gas particles will help you understand the macroscopic properties of a gas.
11. The Ideal Gas Law and the Gas Constant
Have you ever wondered why the pressure in your car's tires is higher after you have been driving a while? In this lesson, we are going to discuss the law that governs ideal gases and is used to predict the behavior of real gases: the ideal gas law.
12. 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.
13. 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.
14. 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.
15. 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.
