Question

Give reason-solids have definite shape and are highly rigid, while gases have no definite shape and are least rigid

Answer 1

Its because solids particles have extremely high interparticular force of attraction and extremely less interparticular spaces and so are incompressible and hence dont change their shape or we can say they are rigid. On the contraray, gas particles have very weak interparticular forces of attraction and hence the particles overcome it and move freely and occupy all the volume of the container they are in and are least rigid

Answer 2

Answer:

Explanation:

In solids, the intermolecular spaces are negligible and the atoms move about in their own position which gives solids a definite shape and makes them rigid while in gases, the intermolecular spaces are large which allows the atoms to move around freely and hence, they are least rigid and have no definite shape.
