What property do gases exhibit when placed in a container?

Gases exhibit the property of uniformly filling the container they are in due to their low density and high kinetic energy. Unlike liquids and solids, gas particles are far apart and move freely in all directions. This motion is largely due to the collision of particles with each other and the walls of their container, allowing the gas to spread out and occupy every available space. This behavior results from decreased intermolecular forces and allows gas to expand until it evenly distributes itself throughout the entire volume of the container.

In contrast, liquids tend to maintain a fixed volume but take the shape of the part of the container they occupy, while solids retain both shape and volume. Therefore, gases do not conform to the behavior of remaining at the bottom or occupying corners, which results from the unique characteristics of gas particles and their interactions.
