rigidity
compressibility
fluidity

Answer 1

_________________________


$\sf{\underline{1)\:Rigidity:}}$

Rigidity is the property of a solid body to resist deformation.


$\sf{\underline{2)\:Compressibility:}}$

Compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure change.


$\sf{\underline{3)\:Fluidity:}}$

The ability of the fluids (liquids and gases) to flow is called fluidity.
