Question

give reason that the molecules are closely packed with each other​

Answer 1

Answer:

In the solid-state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume and molecules are most tightly packed in solids.Most solids are hard, but some (like waxes) are relatively soft .Many solids composed of ions can also be quite brittle.
