Question

Difference between rigidity and compressibility

Answer 1

rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy and density.Rigidity: It is the property of matter to resist the change of its shape. Compressibility: It is the property of matter in which its volume is decreased by applying force. Fluidity: It is the ability of matter to flow

Answer 2

Rigidity is nothing but the resistance offered to prevent change in shape
(Solids have this property)
Compressibility is the property of liquids and gases which makes it easier to change their shape by applying pressure.
It is possible to liquify gases due to their high compressibility.
