Matter is anything has mass and takes up space (has volume)
What is matter?

Matter is anything has mass and takes up space (has volume)
There are three different states or phases of matter:

Matter is anything has mass and takes up space (has volume)
There are three different states or phases of matter: Solid – definite shape and volume

In order to understand further the properties of these phases, you need to get down to the particle level.

The particle model has 3 key ideas:1) All substances are made up of tiny particles.2) The particles are always in motion. They will
move faster as energy is added or slow down as energy is taken away.

Actually, there are 2 more key ideas but we’ll get to those later…

Solids Particles are tightly packed and moving with
mainly a vibrational motion. Very low energy.

Liquids Particles are vibrating and rotating and so
there are bigger spaces between them. The particles don’t form rigid clumps which is
why they take the shape of the container they are in.

Gases Particles have very high energy and so have
rotational, vibrational and translational movement.
There are large spaces between the particles.

As the particles gain or lose energy, they move closer or further apart.
This change in energy results in changes of state.
