Chapter 19, Problem 8RQ

Interpretation Introduction

Interpretation: The definition of fusion and fission is to be stated. The comparison between energy associated with fusion or fission process and chemical reactions is to be done. The reason for fusion processes to be suitable for lighter elements and fission process for heavier elements is to be stated. The reason for the requirement of elevated temperatures to initiate fusion reactions but not fission reaction is to be stated.

Concept introduction: In nuclear reactions, tremendous amount of energy is released. Any substance will melt down at such high temperature. Fusion processes are more likely to occur for lighter elements whereas, fission process are more likely to occur for heavier elements.

To determine: The definition of fusion and fission, the comparison between energy associated with fusion or fission process and chemical reactions, the reason for fusion processes to be suitable for lighter elements and fission process for heavier elements and requirement of elevated temperatures to initiate fusion reactions but not fission reaction.
