a.why are solids are rigid
Answers
The atoms in solids are held together by interatomic forces. The average location of the atoms in a lattice does not change with time. Since the atoms are almost lacking in mobility, their kinetic energy is negligibly small. It is this lack of mobility which makes a solid rigid.
Answer:
Solids are rigid because of the force of attraction.
Explanation:
As you might have seen in many diagrams, solids, liquids and gases have the least, more and most intermolecular gap, respectively. It's the force of attraction between the molecules in different states of matter that give them their shape. Now that the molecules of solids are packed really tightly, the intermolecular gap is the least in them and is not enough for any object to easily penetrate through them. That is why they are considered rigid.
