Chemistry
Chemistry is sometimes called “the central science,” because it bridges physics with other
natural sciences, such as geology and biology
...
Matter is simply anything that occupies
space and has mass
...
Physical properties are characteristics that describe matter
...
They are classified as extensive and intensive properties
...
Extensive properties depend on amount of substance like mass, volume,
weight, and length
...
An example of a chemical property is flammability—a
material’s ability to burn—because burning (also known as combustion) changes the chemical
composition of a material
...
There are two types of substances
...
Aluminum, which is used in
soda cans, is an element
...
Water is a compound
composed of the elements hydrogen and oxygen
...
In contrast, scientists have identified tens of millions of different compounds
to date
...
By
definition, any single substance is pure
...
Atoms are extremely tiny; to make a line 1 inch long, you would need 217 million iron
atoms
...
Molecules are composed of atoms that are attached together and behave as a unit
...
When a
scientist is working with large numbers of atoms or molecules at a time, the scientist is studying

the macroscopic view of the universe
...
Mixtures
A material composed of two or more substances is a mixture
...
Many mixtures are obvious combinations of two
or more substances, such as a mixture of sand and water
...
In some mixtures, the components are so intimately combined that
they act like a single substance (even though they are not)
...
Sugar dissolved in
water is an example of a solution
...
Air, a mixture of mainly nitrogen and oxygen, is a gaseous solution
...
These three descriptions, each implying that the matter has
certain physical properties, represent the three phases of matter
...
Liquids ordinarily have a definite volume but not a definite shape; they
take the shape of 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)
...
Finding practical applications of concepts and skills in daily living
Classify some substances found in the kitchen and in the bathroom as pure substances
or mixtures; elements or compounds; and homogeneous or heterogeneous mixture
...
H
...
• Matter can exist in one of three main states: solid, liquid, or gas
...
Pure
substances are further broken down into elements and compounds
...
• A chemical substance is composed of one type of atom or molecule

A heterogeneous mixture is a mixture of two or more chemical substances where the
various components can be visually distinguished

Elements cannot be divided into smaller units without large amounts of energy
