The test tube which contains gas has the highest volume.
The volume of gases is greater than that of solids and liquids. Notably, gases and liquids both take on the shape of a container due to the atom's free arrangement in both of these states of matter. It s because of the increased volume of gases.
The molecules in solids are typically denser than those in liquids or gases because they are packed closer together. Densities are higher for solids. Thus, solids with atoms arranged in a closed system result in a less volume being occupied. The atoms were loosely packed in liquids. As a result, liquids have a higher volume occupancy than solids since they have atoms organized loosely.
Although they liquids have a specific volume, liquids adopt the shape of the container. Gases lack a consistent shape or volume.
Therefore, Gases have largest volume as compared to solid and gas.
