Gasses fill up any available space as they don’t have a definite shape. a. true b. false

True

Explanation: Matter exists in three states: liquid, solid and gas.

In gases, the molecules are very far apart because the forces of attraction between them are negligible. Therefore the molecules of a gas move randomly, colliding with one another and with the walls of the container. Because of the negligible forces of attraction between the gas molecules, they move randomly and do not have a definite shape, rather assumes the shape of their container.
