Question

List the characteristic physical properties of the gases.

Answer 1

Characteristic physical properties of the gases:

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