1.1 understand the arrangement, movement and energy of the particles in each of the three states of matter: solid, liquid and gas
As the picture shows, all the particles in a solid are touching. Another feature of a solid is that the particles aren't moving, the particles have no energy.
Liquid particles are, like solids, all touching. The difference is that liquid particles are moving- they flow to fit the space- this means that they have some energy.
In gasses the particles aren't all touching; they are far apart. They move freely and have a high energy level.
