    • Solids have a fixed volume and shape and they have a high density.
    • The atoms vibrate in position but can’t change location
    • The particles are packed very closely together in a fixed and regular pattern
    • Liquids also have a fixed volume but adopt the shape of the container.
    • They are generally less dense than solids (an exception is water),but much denser than gases.
    • The particles move and slide past each other which is why liquids adopt the shape of the container and also why they are able to flow freely
    • Gases do not have a fixed volume, and, like liquids,take up the shape of the container.
    • Gases have a very low density.
    • Since there is a lot of space between the particles,gases can be compressed into a much smaller volume.
    • The particles are far apart and move randomly and quickly(around 500 m/s) in all directions.
    • They collide with each other and with the sides of the container(this is how pressure is created inside a can of gas).
