Properties of Solids


Ice, wood, coal, stone, iron, brick, etc., are some of the common solids around us. The solids have the following characteristic properties :
1.Solids have a fixed shape and a fixed volume.
2.Solids cannot be compressed much.
3.Solids have high densities. They are heavy.
4.Solids do not fill their container completely.
5.Solids do not flow.
