Ch 4: Praxis Middle School Science: Thermodynamics

About This Chapter

If you need to renew your knowledge of thermodynamics for the Praxis Middle School Science test, then this chapter can help. It covers all of the essentials of thermodynamics that you'll face on the test through upbeat video lessons taught by professionals.

Praxis Middle School Science: Thermodynamics - Chapter Summary

This comprehensive chapter breaks down the fundamentals of thermodynamics in fun, easy-to-follow video lessons. Take our videos with you and watch on-the-go wherever you are. Our subject-matter experts bring to life topics such as convection, radiation, and conduction, and they help you review key concepts, like:

  • Heat vs. temperature
  • Heat and phase changes, heating curves and energy diagrams
  • Working with endothermic and exothermic reactions
  • The thermal expansion equation
  • Thermodynamics-related laws
  • Efficiency and examples of the Carnot cycle

This chapter was developed by science experts who want to help you get ready for the Praxis Middle School Science exam.Watch all of the lessons in one sitting, or view a portion of a single video and pick up where you left off at a later time. Finish each lesson with a short quiz and our final chapter test to see how well you remember the material.

6 Lessons in Chapter 4: Praxis Middle School Science: Thermodynamics
Test your knowledge with a 30-question chapter practice test
Endothermic and Exothermic Reactions

1. 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.

Thermal Expansion: Definition, Equation & Examples

2. 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.

The Zeroth Law of Thermodynamics

3. 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.

The Laws of Thermodynamics

4. 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.

Efficiency & the Carnot Cycle: Equations & Examples

5. 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.

Heat Transfer & Phase Changes

6. 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.
