You should know that intermolecular forces give the physical properties of gases, liquids and solids.
You should notice that the distances between gas molecules are much larger than distances between liquid molecules, hence the intermolecular forces are weak. Since intermolecular forces are weak, the gases have no shape but they tend to have the form of storage chamber. Notice that the compressibility property of gases is due to large distances between molecules.
Like gases, liquids tend to have the form of storage chamber, but not the volume. Unlike gases, the liquids are not so easily compressed because the distances between molecules are smaller than in gases.
The solids have their own shapes and volumes because the distances between molecules are too small, hence intermolecular forces are strong. The compression forces need to be stronger than intermolecular forces for solids to suffer a change in arrangements of particles.
