Chapter 1, Problem 1.8P

(a)

Interpretation Introduction

Interpretation:

Whether the fuel in the car or the gaseous products in its exhaust has higher potential energy is to be determined.

Concept introduction:

Energy is defined as the capacity to do work. It is associated with both physical and chemical changes.

The two types of energy are as follows:

1. Potential energy: It is the energy due to the position of the object relative to the other objects.

2. Kinetic energy: It is the energy that arises due to the motion of the objects.

(b)
