Question
A gas has neither a definite volume nor a definite shape. Describe the molecular model to explain it.

Solution
Here the molecules are far apart from each other i.e. have the greatest intermolecular distance which results in the weakest intermolecular forces of attraction. The molecules as are not
bound by any strong force move about freely and thus gases do not have a definite shape and also do not have any definite volume.
