Question

Distinguish between the three stoles
of Matter - Soild, Liquid, and has
on the basis of thier Molecular
models.​

Answer 1

Explanation:

Solids :

Here the molecules are very tightly packed that there is no or very less inter-molecular space and there is high inter-molecular force of attraction (force of cohesion).

The molecules do not move about their mean position and thus solids have a definite shape and volume.

Liquids :

Here the molecules are less tightly packed as compared to solids and also there is lesser force of inter-molecular attraction. The inter-molecular 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.

Gases :

Here the molecules are far apart from each other i.e. have the greatest inter-molecular distance which result into the weakest inter-molecular 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.
