Question

Why does a gas fill a vessel completely ?​

Answer 1

Gases have a negligible intermolecular force of attraction between the particles of gas. The random motion of particles in all the directions is experience in the vessel. Hence, the gas fills completely the vessel in which it is kept.

Answer 2

Answer:

Gases have a negligible intermolecular force of attraction between the particles of gas. The random motion of particles in all the directions is experience in the vessel. Hence, the gas fills completely the vessel in which it is kept.The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid
