Why are gases compressible whereas solids are not compressible?

Question

Quizplus · Accepted Answer

The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
In solids, the atoms or molecules are closely packed together, so they are very dense and are held together by strong intermolecular forces of attraction. When we put pressure on solids, to compress them, there no space between the atoms/molecules and as a result we cannot compress them.
