Chapter 17.1, Problem 11LC

Interpretation Introduction

Interpretation: The reason how energy is conserved during the conversion of gasoline in a car engine is to be found.

Concept Introduction : According to the law of conservation of energy, during a physical or chemical process energy can neither be created nor be destroyed. It can only change from one form to another.

Answer to Problem 11LC

The chemical energy of gasoline is converted into heat energy, which is then converted to kinetic energy.

Explanation of Solution

The chemical energy stored in the chemical bonds of the gasoline is converted into heat energy. The engine then helps to convert heat energy into kinetic energy, which helps in the motion of the vehicle.
