Gases are all around us, but although many, such as perfume, can be smelt, most gases are invisible. Like liquids, gases can flow but, unlike solids or liquids, gases will not stay where they are put. They have no set shape or volume, and they expand in every direction to fill completely whatever container they are put into.

If the container has no lid, the gas escapes. Some materials can be changed. They can be mixed with other materials for example when the ingredients are mixed together to make a cake and then changed again by heating.

Some changes, though, are reversible. For example, when ice is heated it melts and becomes water, but this change can be reversed by re-freezing the water into ice. Some materials are particularly well-suited to a certain job. For example, certain kinds of metal, such as copper or aluminium, are extremely efficient conductors of electricity this means electricity passes well through them.

Therefore, these are the metals most likely to be used for electrical cables. Because plastic and rubber do not conduct electricity, they are used to wrap the cables of electrical items we use around the house.

A solution is a specific type of mixture where one substance is dissolved into another. A solution is the same, or uniform, throughout which makes it a homogeneous mixture. One example of a solution is salt water which is a mixture of water and salt. You cannot see the salt and the salt and water will stay a solution if left alone.

A solution is made when one substance called the solute " dissolves " into another substance called the solvent. Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. This break-up is caused by coming into contact with the solvent.

Matter can change from one state to another if heated or cooled. If ice a solid is heated it changes to water a liquid.
