Arrangement Regular Irregular Random
Movement Cannot move, vibrate Particles can move Particles can move
only throughout the liquid freely
slight past each other
Energy of Particles Particles have least Particles have more The particles have the
kinetic energy kinetic energy than most kinetic energy
solid
Distance between Closely packed Not closely paced Far apart
particles
Shape 3D structure Takes the shape of the No fixed shape
container
1.2 understand how the interconversions of solids, liquids and gases are achieved and recall the names
used for these interconversions
