solids
Solid
rock is a solid so the physical properties are that of solids rigid definite mass and volume that is definite density cannot flow incompressible there are exceptions
There are three states of matter, solid, liquid and gas. The state of matter wherein particles are fixed in a rigid structure is solid.
No. A triangle is the only rigid polygon.
Solids. They are most resistant to outer forces; but strictly speaking all materials are compressible.
Solids are incompressible because the atoms or molecules that make up a solid are already closely packed together. When an external force is applied to a solid, the atoms resist being pushed closer together due to their strong intermolecular forces and rigid structure, making them difficult to compress.
Gas and liquid are not rigid.
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.

No, water is not completely incompressible, but it is very difficult to compress compared to other substances.
The only convex polygon that is rigid is a triangle.
The solid state of matter is the most rigid because the particles are closely packed together and have little room for movement. This results in a fixed shape and volume, making solids resistant to deformation.
