Give Reason: A Gas fills completely the vessel in which it is kept.

A Gas fills completely the vessel in which it is kept as it has a negligible intermolecular force of attraction between the particles. As it is loosely bound, the random motion occurs in all directions inside the vessel which makes it fit the vessel. The intermolecular force of attraction between the particles in gases is quite weak.

Due to the weakly linked gaseous particles, the vessel experiences random motion of the particles in all directions, causing the vessel to fill with gas. Therefore, a gas entirely fills the container in which it is kept since there is no intermolecular force of attraction between the particles.

Physical Properties of Gases

  • Compared to solids and liquids, gases are both more compressible and have a lower density.
  • They apply the same amount of pressure everywhere.
  • Gas particles have a large interparticle distance and high kinetic energy.
  • These gas particle intermolecular forces are insignificant.
  • These particles collide as they travel at high speeds in all directions, distributing the gas uniformly across the container they are maintained in. They press on the container's walls as a result of this.
  • As a result, gases adopt the container's shape and volume.

Summary:

Give Reason: A Gas fills completely the vessel in which it is kept.

A gas entirely fills the container in which it is contained since there is little intermolecular interaction between the particles. Because it is loosely bound, random motion happens inside the vessel in all directions, causing it to fit the vessel.
