Gases, liquids and solids
Introduction
Solids, liquids and gases have different properties.
Liquids and gases can flow. Solids keep their shape. Gases can be squashed
Gases
Gases are often invisible.
Gases do not keep their shape or always take up the same amount of space. They spread out and change their shape and volume to fill up whatever container they are in.
Gases can be squashed.
Heating a liquid can turn it into a gas.
Cooling a gas can turn it into a liquid.
Examples of gases
Liquids
Liquids can flow or be poured easily. They are not easy to hold.
Liquids change their shape depending on the container they are in.
Even when liquids change their shape, they always take up the same amount of space. Their volume stays the same.
Heating a liquid can turn it into a gas.
Cooling a liquid can turn it into a solid.
Heating a solid can turn it into a liquid.
Cooling a gas can turn it into a liquid.
Examples of liquids
Solids
Solids stay in one place and can be held.
Solids keep their shape. They do not flow like liquids.
Solids always take up the same amount of space. They do not spread out like gases.
Solids can be cut or shaped.
Even though they can be poured, sugar, salt and flour are all solids. Eachparticle of salt, for example, keeps the same shape and volume.
Heating some solids can turn them into liquids.
Cooling a liquid can turn it into a solid.
