Chapter 21.2, Problem 21.1CE

Incorrect. Heat is not contained in Texas. The high temperature in Texas means that the air has a lot of thermal energy. b. Incorrect. Kinetic energy is converted into thermal energy due to friction between the table and the book. c. Incorrect. Heat and work are both methods of transferring energy. One does not become the other.

Decide which of the following statements are incorrect according to the definition of heat used in physics. Explain your answers and provide corrections where possible.

1. a. “The heat in Texas will make you tired.”
2. b. “When you slide a book across a table, kinetic friction converts kinetic energy into heat.”
3. c. From a science textbook: “The steam engine marked the first time in human history that heat was used to do work.”
