En -Schaums Thermodynamics for Engineers

Preface

The authors of this book have

many years of experience

teaching general chemistry

and other areas of chemistry at the

college level. Although we have

been at different institutions, both

large and small, during our careers,

we share several goals. One is to provide

a broad overview of the principles

of chemistry, the reactivity of

the chemical elements and their

compounds, and the applications of

chemistry. To reach that goal with

our students, we have tried to show

the close relation between the observations

chemists make of chemical

and physical changes in the laboratory and in nature and

the way these changes are viewed at the atomic and molecular

level.

Another of our goals has been to convey a sense that

chemistry not only has a lively history but is also dynamic,

with important new developments occurring every year.

Furthermore, we want to provide some insight into the

chemical aspects of the world around us. Indeed, a major

objective of this book is to provide the tools needed for

you to function as a chemically literate citizen. Learning

about the chemical world is just as important as understanding

some basic mathematics and biology and as

important as having an appreciation for history, music,

and literature. For example, you should know what materials

are important to our economy, some of the reactions

in plants and animals and in our environment, and

the role that chemists play in protecting the environment.

In this regard, one growing area of chemistry,

highlighted throughout this edition, is “green” or sustainable
