Section 1: Chemistry and Matter What is Chemistry? Everything around us is made up of chemicals. From the color that makes a rose so red to the gasoline that fills our cars and the silicon chips that power our computers and cell phones…Chemistry is everywhere! Understanding how chemical molecules form and interact to create complex structures enables us to harness the power of chemistry and use it, just like a toolbox, to create many of the modern advances that we see today. This includes advances in medicine, communication, transportation, building infrastructure, food science and agriculture, and nearly every other technical field that you can imagine.

Chemistry is one branch of science. Science is the process by which we learn about the natural universe by observing, testing, and then generating models that explain our observations. Because the physical universe is so vast, there are many different branches of science Figure 1. Thus, chemistry is the study of matter, biology is the study of living things, and geology is the study of rocks and the earth. Mathematics is the language of science, and we will use it to communicate some of the ideas of chemistry. Although we divide science into different fields, there is much overlap among them. For example, some biologists and chemists work in both fields so much that their work is called biochemistry.

Similarly, geology and chemistry overlap in the field called geochemistry. Figure 1. Chemistry lies more or less in the middle, which emphasizes its importance to many branches of science. Physical vs. Chemical Properties Part of understanding matter is being able to describe it. One way chemists describe matter is to assign different kinds of properties to different categories. The properties that chemists use to describe matter fall into two general categories. Physical properties are characteristics that describes matter, such as boiling point, melting point and color. Physical Changes, such as melting a solid into a liquid, do not alter the chemical structure of that matter. Chemical properties are characteristics that describe how the chemical structure of matter changes during a chemical reaction.

An example of a chemical property is flammability—a materials ability to burn—because burning also known as combustion changes the chemical composition of a material. Elements and Compounds Any sample of matter that has the same physical and chemical properties throughout the sample is called a substance. There are two types of substances. A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components because it has more than one element is a compound. Water is a compound composed of the elements hydrogen and oxygen. Today, there are about elements in the known universe which are organized on a fundamental chart called the Periodic Table of Elements Fig.

In contrast, scientists have identified tens of millions of different compounds to date. The smallest part of an element that maintains the identity of that element is called an atom. Atoms are extremely tiny; to make a line 1 inch long, you would need million iron atoms! Similarly, the smallest part of a compound that maintains the identity of that compound is called a molecule. Molecules are composed of atoms that are attached together and behave as a unit Fig.

Scientists usually work with millions of atoms and molecules at a time. When a scientist is working Figure 1. Lower Panel To the left of the arrow is shown one atom of oxygen and two atoms of hydrogen. Each of these represent single elements. When they are combined on the righthand side, they form a single molecule of water H2O. Note that water is defined as a compound, because each single molecule is made up of more than one type of element, in this case, one atom of oxygen with two atoms of hydrogen. However, scientists can also describe chemical events on the level of individual atoms or molecules, which is referred to as the microscopic viewpoint.

We will see examples of both macroscopic and microscopic viewpoints throughout this book Figure 1. Although we do not notice it from a macroscopic perspective, matter is composed of microscopic particles so tiny that billions of them are needed to make a speck that we can see with the naked eye. The X25 and X,, indicate the number of times the image is magnified. Mixtures A material composed of two or more substances is a mixture. In a mixture, the individual substances maintain their chemical identities. Many mixtures are obvious combinations of two or more substances, such as a mixture of sand and water. Such mixtures are called heterogeneous mixtures. In some mixtures, the components are so intimately combined that they act like a single substance even though they are not. Mixtures with a consistent composition throughout are called homogeneous mixtures Homogeneous mixtures that are mixed so thoroughly that neither component can be observed independently of the other are called solutions.

Sugar dissolved in water is an example of a solution. A metal alloy, such as steel, is an example of a solid solution. Air, a mixture of mainly nitrogen and oxygen, is a gaseous solution. Homogeneous Mixtures. A mixture contains more than one substance. In the upper panel you see an example of a heterogeneous mixture of oil and water. The mixture is heterogeneous because you can visibly see two different components in the mixture. In the lower panel, you see an example of a homogeneous mixture, coffee. It is homogeneous because you cannot distinguish the many different components that make up a cup of coffee water; caffeine; coffee alkaloids and tannins.

It looks the same throughout. If the mixture is homogeneous and is also see through or clear, it is called a solution. In our example, the coffee is a solution; however, a concentrated espresso may be very opaque and would only be homogeneous mixture, not a solution. States of Matter Another way to classify matter is to describe it as a solid, a liquid, or a gas, which was done in the examples of solutions, above. These three descriptions, each implying that the matter has certain physical properties, represent the three phases of matter.

A solid has a definite shape and a definite volume. Liquids have a definite volume but not a definite shape; they take the shape of their containers. Gases have neither a definite shape nor a definite volume, and they expand to fill their containers. We encounter matter in each phase every day. In fact, we regularly encounter water in all three phases: ice solid , water liquid , and steam gas. We know from our experience with water that substances can change from one phase to another if the conditions are right. Typically, varying the temperature of a substance and, less commonly, the pressure exerted on it can cause a phase change or a physical process in which a substance goes from one phase to another Figure 1. Phase changes have particular names depending on what phases are involved, as summarized in Table 1. Analyzing Phase Changes. Upper panel A photo of boiling water demonstrates the phase change of water from the liquid to the gaseous phase.

Note that phase changes are a physical property of a molecule. The water is still chemically the same H2O in the solid, liquid, or gaseous state. Lower panel Change in temperature can cause phase changes. Above is the temperature scale for the phase changes of water. If you add heat to solid ice, water will melt at 0oC and boil at oC. If you remove heat from gaseous water, it will condense into the liquid state at oC and freeze at 0oC. In summary, Figure 1. Generally, they follow a process called the scientific method. The scientific method is an organized procedure for learning answers to questions. The steps may not be as clear-cut in real life as described here, but most scientific work follows this general outline. Propose a hypothesis. A scientist generates a testable idea, or hypothesis, to try to answer a question or explain how the natural universe works. Some people use the word theory in place of hypothesis, but the word hypothesis is the proper word in science.
