Question

5.
Why do solids have a regular geometrical shape?
​

Answer 1

Answer:

Because the particles in solids have maximum force of attraction between them . Solids may break under force but it is difficult to change their shape , so they ate rigid and have a regular geometrical shape . In solids particles are closely packed and have strong interparticle forces of attraction.

Hope it's helpful for you.

Answer 2

Answer:

In solids, the particles have highly ordered arrangement because the intermolecular forces between the particles are very strong. Therefore, solids have a regular geometrical shape
