Answer:
Comment upon the following: rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy, and density, Rigidity: Rigidity is property shown by solids. It relates to tendency of solids to resist any change in their shape when an external force is applied. ... Solids and liquid are incompressible.
Solid is considered to be the most wizard among the other three matters because in resident in the molecules are very much tightly packed and there cannot be pressed they have fixed shape and size.
whenever any substance can be compressed and their shape can be changed this is known as compressibility.
whenever any matter of a substance flows this is known as fluidity .liquid and gas are considered as the best fluid.
whenever a gas is filled in a container the container is said to be completely filled as a gas exerts pressure on the wall of the container.
the rate at which molecules present in the matter flow is known as kinetic energy and kinetic flow.
Density is mass per volume and its SI unit is kg per metre cube.
I hope my answer will help you.
