Chapter 21: Thermodynamics

Study Plan

As we learn about machines that generate mechanical energy, we can ask:

  • How do we measure the efficiency of an engine, and how efficient is a typical steam engine? (Example 2, page 666)
  • How efficient could an ideal steam engine be? (Example 4, page 671)
  • How does a practical steam engine differ from an ideal engine in operation? (Section 21.2, page 671)

Organize

  1. Prepare for lecture by reading the assigned sections from Chapter 21 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.
  2. Take the checkup quiz and work the Checkup questions in your textbook to assess your understanding of basic concepts. Take note of any topics you need to review further.
  3. Review the Examples from your textbook. These progress from simple to complex, and provide concrete illustrations of the concepts discussed.
  4. Review the Problem Solving Techniques box on Thermodynamic Calculations from your textbook.

Learn

  1. Re-read Chapter 21 and review your lecture notes.
  2. Access the Online Concept Tutorials given for this chapter. Tutorials use animation and interactive exercises to help develop your understanding of fundamental topics.
