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.
