What will happen to the potential energy of the atoms of a solid when
(i) compressed ? (ii) on stretching a wire?

Explanation

To understand what happens to the potential energy of the atoms in a solid when it is compressed or stretched, we can analyze each scenario step by step.

### Step-by-Step Solution:

**Step 1: Understanding Potential Energy in Solids**
- Every solid has a certain arrangement of atoms that corresponds to a minimum potential energy state. This is the state where the forces between the atoms are balanced, and the system is stable.

**Step 2: Effect of Compression on Potential Energy**
