ATI TEAS SCIENCE – CHEMISTRY
Questions related to chemistry test your knowledge of chemical properties and processes. You may be asked question
about states of matter, properties of matter, phase changes, chemical bonds, chemical solutions, chemical reactions, an
acids and bases. You may be asked to balance chemical equations.
Let’s get started in understanding how chemistry is important on the ATI TEAS.

UNDERSTANDING STATES OF MATTER
Matter is made up of microscopic particles that move different speeds
depending on the energy they are exposed to. We measure this energy
as temperature. The molecules can move either quickly and randomly or
hardly at all.
When the energy is high, matter take the form of a gas, in which
molecules are moving about quickly and are far apart. Gases have no
fixed form. Molecules are free to move at random past each other, and
they tend to fill any container that holds them. If a gas is not contained,
its molecules will disperse. PHOTO CREDIT: LIVE SCIENCE

UNDERSTANDING STATES OF MATTER
Lower temperatures result in a liquid, in which molecules cohere but
are fluid. Coherence means that the molecules remain close together,
but they can change position by sliding over one another. In liquids,
molecules move less freely than in a gaseous state, sliding past one
another. They have a fixed volume but will flow freely unless they fill a
portion of a container.
When the temperature is low, matter takes the form of a solid, in which
molecules are packed closely together and retain their positions. Solid
matter is rigid, and molecules retain a uniform spacing. A solid has a PHOTO CREDIT: LIVE SCIENCE
defined form, which is brittle. It can be broken into pieces but tends to
stay together.
A somewhat unusual state of matter is plasma, which is like a gas in
many of its properties but carries an electric charge.
The TEAS focus on solids, liquids, and gases.
