Worksheet Overview

Ice, steam and water - they are all made up of the same stuff!

Although they are all are made out of water particles, the solid, liquid and gaseous states of water have quite different properties. This is because of the way their particles are arranged.

 

particles in solids, liquids and gases

 

In a solid, the tiny particles that make up the solid are very close together in a neat regular arrangement, all touching each other and moving only by vibrating on the spot. They cannot move much at all as there are strong forces of attraction between the particles, which explains why solids have a fixed shape.

 

The particles in a solid don't have much energy. They don't have enough energy to break the forces between them. This is why solids have the properties they do.

The particles in a liquid are arranged in a more random way. They are close together, most of them touching each other, but there are some small gaps. The particles also have more energy than in solids. So the particles can move around a little, over each other, allowing liquids to flow and be poured. This is the reason why liquids take the shape of the container they are in. 

 

The particles are able to move around more than in a solid as they have more energy. The more energy particles have, the more easily they can break the strong forces that normally hold them together, so they can get further apart the more energy they have.

The particles in a gas are spaced very far apart, move around very fast and they are randomly arranged. This is because the particles have lots of energy. So much energy in fact that they can easily overcome the strong forces trying to hold them together, meaning they can move as far apart as they like from each other! Because of this, gases can be easily compressed, or squashed - they have no fixed shape or volume.
