Solids, Liquids and Gas
Solids:
The atoms are packed tightly and closely together under this form of matter. Most solid objects are hard in nature. Examples of solids are ice cubes, iron, wood etc. We establish that atoms posses the properties of the elements they make up, therefore all solids will have different properties. Some solids are stronger than others and cannot bend or break easily.
Liquids:
Atoms here are not tightly packed together like that of solids but they are still quite close. The atoms move freely so solid objects can enter the liquid easily. Liquids can easily mix with other liquids and can take the shape of the container they may occupy. When a liquid is poured from one container to another it may change its shape but the volume remains the same.
Gases:
Atoms are very far apart and move around randomly. Gases are all around us in the atmosphere that surrounds the earth. Examples of gases are oxygen, carbon dioxide and water vapor just to name a few. Like liquids gases can fill up and take the shape of any container. Gases can be compressed and squeezed. Gases are not bound to earth by gravity like solids and liquids.
