Question

In the spring-ball model of intermolecular forces, the balls represent ______ and springs represent ______________.

• A. atoms, inter atomic forces
• B. nuclei, nuclear forces
• C. masses, gravitational forces
• D. none of the above

Answer 1

The correct option is A atoms, inter atomic forces

$Answer:-$ A

In a solid, each atom or molecules surrounded by neighboring atoms or molecules. These are bonded together by inter atomic or intermolecular forces and stay in a stable equilibrium position. When a solid is deformed, the atoms or molecules are displaced from their equilibrium positions causing a change in the inter atomic (or intermolecular) distances.
When the deforming force is removed, the inter atomic forces tend to drive them back to their original positions. Thus the body regains its original shape and size. The restoring mechanism can be visualized by taking a model of spring-ball system shown in the Figure . Here the balls represent atoms and springs represent inter atomic forces.
