Whether the entropy of the system increases or decreases when gasoline burns in car engine is to be determined. Concept introduction: The entropy is the thermodynamic function that describes the randomness or disorderness of the system. It is represented by S . The direct measurement of entropy is not possible so its change is measured and is known as the entropy change ( Δ S ) . It can be positive, negative or zero.

Question

Chapter 13, Problem 13.38P

(a)

Interpretation Introduction

Interpretation:

Whether the entropy of the system increases or decreases when gasoline burns in car engine is to be determined.

Concept introduction:

The entropy is the thermodynamic function that describes the randomness or disorderness of the system. It is represented by S. The direct measurement of entropy is not possible so its change is measured and is known as the entropy change (ΔS). It can be positive, negative or zero.
