degenerate matter would be incompressible. This would not be ordinarily met with, but is considered to be the material of a neutron star. Where, upon the collapse of a giant star, the gravitational forces would collapse all the neutron matter to a solid.
Fond subject of sci-fi writers, e.g. Larry Niven (I think) wrote a story with the title Neutron Star, which will give a rough guide to the supposed physics.

Solids. They are most resistant to outer forces; but strictly speaking all materials are compressible.

This question seems to have been asked in the reverse order. It is far more likely that someone interested in the subject would ask, "What is the state of matter that has fixed volume but not fixed shape?" The answer to that question is "incompressible". Incompressible means constant in volume despite changes in pressure. A body of water is incompressible but can change shape. We change the shape of a glass of water by drinking it, but we don't change its volume. The matter which fits this "reverse question" is the incompressible fluid (or incompressible flexible solid).To satisfy the question asked, the "thing" has to expand or contract at the same rate in all directions. A cube of material with side length of a metre might expand and become a cube of 1.5 metre side length. It is still a cube but of greater volume. A bubble or balloon which expands or contracts because of a change of temperature or pressure is a valid example. However, "being" a cube or a balloon is not a "state" of matter. It is a contrivance and more a result of its history rather than a state of its material.
No state of matter is incompressible. Solids and liquids tend to be sparingly compressible at common pressures. When you get to pressures found in the core of a neutron star, nothing can withstand the force and the nuclei merge and the electrons are stripped away and the material becomes unimaginably dense--even denser than Sean Penn...whoops, did I say that?
You can compress matter in any state because matter is mostly empty space. However, because it takes so much pressure to compress liquids and solids, they are said to be incompressible. ................. The gaseous state of matter is readily compressible.
Gasses are compressible and liquids and solids are incompressible. Using this information one can surmise that CO2 compressible would be the gas phase of CO2 and CO2 incompressible would be the solid (dry ice) phase of CO2.
Solids are considered incompressible because their particles are already tightly packed and do not easily compress together due to their fixed positions and strong intermolecular forces. Liquids and gases are compressible because their particles have more freedom to move and can be compressed closer together.
If it were a solid at room temperature, then that would be the state of matter. However, hydrogen is NOT solid at room temperature. It is a gas and that would be the state of matter.
The liquid phase of matter is a state in which particles have enough energy to move and flow past each other but are still close enough to maintain attraction. Liquids have a definite volume but take the shape of their container.
a natural state of matter would be tellurium
