Interpretation:
The properties of gases need to be explained.
Concept introduction:
Gas, solid and liquid are phases of matter.
Answer to Problem 38A
The properties of gases are as follows:
(i) Gases have no definite shape or volume.
(ii) It has low density and can be compressed.
(iii) It performs diffusion and effusion.
(iv) The molecules of gases are in continuous motion.
Explanation of Solution
Gas is
The density of gases is less as compared to solid and liquids thus, they diffuse at faster rate.
Some examples of gases are
