Ch 21: Understanding Heat Transfer

About This Chapter

Boost your knowledge of topics involving heat transfer, including temperature measurement, with this chapter. Use these lessons and quizzes as a mobile, convenient study guide as you prepare for an upcoming placement exam or homework assignment.

Understanding Heat Transfer - Chapter Summary

In this chapter, our instructors define heat and explain how it is different from temperature. The concept of latent heat is introduced, as well as how heat is transferred. How to identify the phase changes that occur during heat transfer is also presented.

As you move through the lessons, you will also learn about calorimetry as a measuring device and how else temperature is measured. This chapter will prepare you to do the following:

  • Understand the practical applications of heat such as thermodynamics
  • Define latent heat and how it affects matter
  • Differentiate between the three ways heat is transferred between objects
  • Solve heat calculations using a simple equation
  • Convert different temperature measurement units

Our mobile-friendly lessons and quizzes have been designed by professional instructors. These study materials are available for your review 24 hours a day, seven days a week. The chapter tests and lesson quizzes can be used to measure how well you understand the subject and to identify where extra study may be needed.
