The property of gases that allows diffusion to occur is:
- Gas molecules spread outwards to fill the container they are in.
When gas molecules are in a container, they move randomly and rapidly in all directions. This random motion causes the gas molecules to spread out evenly within the container, filling the available space. As a result, gases are able to diffuse or spread out from areas of high concentration to areas of low concentration until they are evenly distributed. This property of gases is essential for processes like diffusion to take place efficiently.
In contrast, the statement "Gas molecules will naturally clump together in a container" is not accurate. Gas molecules tend to move freely and independently of each other, leading to their even distribution throughout the container rather than clumping together.
