प्रश्न
Describe the molecular model for a liquid. I-low does it explain that a liquid has no definite shape, but has a definite Volume?
उत्तर
Here the molecules are less tightly packed as compared to solids and also there is the lesser force of intermolecular attraction. The intermolecular distance is greater than that in the solids. Thus, they do not have a definite shape but acquire the shape of the vessel in which they are contained but have a definite volume at a given temperature.
