A Correct answer
Explanation

Gases do not posses any definite shape or volume. They completely fill all the space available to them. The tendency of a gas to fill the available volume within a container is the result of the freedom that gas particles have to move everywhere in the available space. As a result the molecules of gas are in a continuous motion and are associated with high velocity and therefore high kinetic energy.
