STATES OF MATTER Solids, Liquids, Gases, and Plasma

SOLIDS • Solids are one of the basic states of matter. • A solid forms from a liquid or gas because the energy of atoms decreases when the atoms take up a relatively ordered, threedimensional structure. • Solids are rigid, have a fixed shape, and a fixed volume.

LIQUIDS Liquids are one of the basic states of matter A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. Liquids take the shape of the container, have a fixed volume, have a fluid surface.

GASES • Gases are one of the basic states of matter. • Gases are an air like fluid substance which expands freely to fill any space available. • Gases have no definite volume and no definite shape. • Gases fill available space.

PLASMA • Plasma is one of the basic states of matter. • Plasma is an ionized gas consisting of positive ions, and free electrons in proportions resulting in more or less no overall charge, typically at low pressures or at very high temperatures.

The kinetic energy of an object is the energy that it possesses due to its motion. There is kinetic energy in every state of matter. Kinect energy causes the molecules to move faster as the energy increases. In solids there is very little motion because the structure is close together. In liquids the motion increases slightly from that of a solid. In gas the motion increases slightly from that of a liquid. In plasma the motion has increased significantly. KINECT ENERGY
