The Particle Theory Of Matter Is Where ....
Matter is made of particles that are invisible called atoms or molecules they are too small to examine with a naked eye. The molecules are attracted to each other. They are also in motion all the time and they have space between them. The amount of space between them is different for each state. For example; particles in a liquid have more space between each other compared to a solid. The particles move faster when the temperature increases and move slower when the temperature decreases.

The Particle Theory of Matter
The difference between pure substances and mixtures is that pure substances are made up of one type of substance
and a mixture is a combination of two or more substances. Also the particle theory of matter says that particles have space between them, the particles in a pure substance have very little space between each other and in a mixture there are more space between them.
substance that has mass and takes up space.
Solid: Matter that has shape and volume, it's particles are tightly.
Liquid:Matter that only has volume. It's particles can move around but they are close to each other.
Gas:Matter that does not have mass nor volume.It's particles can move freely and they have a lot of space between each other.

Particles in a solid are very close to each other and they can't maneuver around. The particles are also consonantly vibrating but they can't move from one place to another. They are incompressible because they make a fixed shape. A solid has vibrational energy.
Particles In a Liquid
Particles in a liquid have
more space between them
than the particles in a
solid.They can slip past
each other. They are incompres-
sible. A liquid has
which gives it the capability
to flow and spread.
Particles In a Gas
in a gas have
more between them
space compared to a
liquid.They can move in
any direction.The particles have
rotational, translational and vibrational energy. They are not affected by gravity. They con be compressed. They have high kinetic energy.
