Gases do not have a definite shape.
(1)In gases, the intermolecular forces of attraction are very weak, almost negligible.
(2)They cannot hold the gas molecules together.
(3)The molecules of gases constantly move away from one another.
(4)They spread out or flow in all directions to fill the space available to them.
Thus, gases neither have a definite shape nor a definite volume.
Therefore, the given statement is true.
