States of Matter

There are four main types of matter: Plasma, Gas, Solid, Liquid.

Plasma - Plasma is created by adding energy to a gas so that
some of its electrons leave its atoms. It results in negatively
charged electrons, and positively charged ions. Unlike the
other states of matter, the charged particles in a plasma will

react strongly to electric and magnetic fields.

Gas - Gas is a state of matter that has no fixed shape and no fixed
volume. Gases have lower density than other states of matter,

such as solids and liquids. The particles exert more force on the
interior volume of the container. This force is called pressure.

Liquid - A liquid is a nearly incompressible fluid that
conforms to the shape of its container but retains a nearly

constant volume independent of pressure. As such, it is one of
the four fundamental states of matter and is the only state
with a definite volume but no fixed shape.

Solid - In solids, the particles are closely packed. Unlike a

liquid, a solid object does not flow to take on the shape of its
container, nor does it expand to fill the entire volume available

to it like a gas does. Solids have a definitive shape and volume.

This video will elaborate upon and explain the states of matter.
