List the characteristic physical properties of the gases.

1.	List the characteristic physical properties of the gases.
Answer» Characteristic physical properties of the gases : Gases are lighter than solids and liquids (i.e., possess lower density). Gases do not possess a fixed volume and shape. They occupy entire space available and take the shape of the container. Gas molecules are widely separated and are in continuous, random motion. Therefore, gases exert pressure equally in all directions due to collision of gas molecules, on the walls of the container. In case of gases, intermolecular forces are weakest. Gases possess the property of diffusion, which is a spontaneous homogeneous inter mixing of two or more gases. Gases are highly compressible.
