Answer
a) Gases do not have any definite shape.
b) They are highly compressible.
c) They have low density.
d) They exert pressure on the walls of the container in which they are kept.
Work Step by Step
Some of the basic properties of gases are as follows-
a) Gases do not have any definite shape and volume. Due to this, they acquire the shape of the container in which they are kept.
b) The molecules of gases are not held together by the strong intermolecular attraction. Due to this gas particles are very dispersed, which give them low density.
c) Due to the large distances between the gaseous particles, gases are much more compressible as compared to solids and liquids.
d) Gaseous particles are in a constant random motion. They strike the walls of the container in which they are kept, thereby exerting a force on it.
