Ch 7: Basics of Thermodynamics

About This Chapter

Use these lessons and quizzes to help you review the basics of thermodynamics. You'll cover different types of energy, changes in heat and energy, laws of thermodynamics and how heat transfer works.

Basics of Thermodynamics - Chapter Summary

This chapter uses brief but informative video lessons to get you up to speed on thermodynamics. You'll start by learning about the basics of energy and then move on to cover a variety of energy types and examples of each. More advanced topics in this chapter include the first and second laws of thermodynamics and calculating heat capacity for different types of substances. By the end of the chapter, you'll have reviewed the following:

  • The significance of energy
  • Mechanical, thermal, radiant, chemical, electrical and nuclear energy
  • Conversion of kinetic energy to potential energy
  • Methods of heat transfer
  • Applications of the laws of thermodynamics
  • Heat and energy diagrams
  • Energy transformations in living organisms

These lessons are a quick and easy way to brush up on key thermodynamics topics. Each concept is clearly explained in short video lessons lasting less than ten minutes apiece. Watch the lessons as many times as you need until you've fully grasped the information presented. You can also use the lesson quizzes and chapter exam to assess your understanding of lesson material and target the areas where you need to focus.

12. 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.

How to Calculate Specific Heat Capacity for Different Substances

13. 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.

Changes in Heat and Energy Diagrams

14. 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.

Energy and Life: The Transformation of Energy in Living Organisms

15. Energy and Life: The Transformation of Energy in Living Organisms

While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.
