Effects
When put under compression (or any other type of stress), every material will suffer some deformation, even if imperceptible, that causes the average relative positions of its atoms and molecules to change.  The deformation may be permanent, or may be reversed when the compression forces disappear. In the latter case, the deformation gives rise to reaction forces that oppose the compression forces, and may eventually balance them.Liquids and gases cannot bear steady uniaxial or biaxial compression, they will deform promptly and permanently and will not offer any permanent reaction force. However they can bear isotropic compression, and may be compressed in other ways momentarily, for instance in a sound wave.Uses
Compression of solids has many implications in materials science, physics and structural engineering, for compression yields noticeable amounts of stress and tension.
By inducing compression, mechanical properties such as compressive strength or modulus of elasticity, can be measured.Compression machines range from very small table top systems  to ones with over 53 MN capacity.
Gases are often stored and shipped in highly compressed form, to save space.  Slightly compressed air or other gases are also used to fill balloons, rubber boats, and other inflatable structures.  Compressed liquids are used in hydraulic equipment and in fracking.
