Answer:
their ability to fill the available volume of a container
Explanation:
Diffusion is the movement of gas molecules from a region of higher concentration to a region of lower concentration. Gasses fill up the volume of a container because gas molecules spread out in empty space. By so doing they fill up the volume of the container. This spreading out is caused by diffusion. Hence this property is explainable by diffusion.
