Chapter 17.1, Problem 5LC

Interpretation Introduction

Interpretation: The ways that energy conversion can occur are to be explained.

Concept introduction: Energy can exist in several forms within a system and can be changed from one form to another under the constraints of conservation law. There are several types of energy, including gravitational, kinetic, electrical, chemical, nuclear, and mass energy.

Answer to Problem 5LC

The transfer of heat or work, or a combination of both, are the ways that can convert energy.

Explanation of Solution

According to the principle of energy conservation, energy cannot be generated or destroyed but may be converted from one form to another. Energy changes occur as a result of heat transfer, work, or a combination of both

Energy may be transformed from one form into another; for example, mechanical energy can be transformed into electrical energy, and electrical energy can be transformed into chemical energy.

Conclusion

The transfer of heat or work, or a combination of both, are the ways that can convert energy.
