Have a fixed volume and shape, high density, atoms vibrate in position but can't change location, particles packed closely together in a fixed and regular pattern
Liquids
Have a fixed volume but adopt the shape of the container, generally less dense than solids, particles move and slide past each other
Gases
Do not have a fixed volume, take up the shape of the container, very low density, a lot of space between the particles, particles move randomly and quickly, collide with each other and the container
Solids, liquids and gases have different physical properties that can be explained by the arrangement and motion of their particles
