Answer:
The solid particles eventually gain so much energy that the vibrations increase and break their fixed positions.
Step-by-step explanation:
Atomic bonds hold atoms to one another inside a solid. Instead of acting like stiff rods, these linkages act like springs. A solid is thus made up of several heavy particles that are linked by springs. You may easily picture these particles continuing to oscillate erratically to and fro from their places, resulting in zero net motion. But power is still needed for this oscillation. The solid's temperature is controlled by this energy, which is also known as internal energy. The energy increases with temperature. A solid's internal net energy rises when it receives (thermal) energy. The surplus is divided among all the particles essentially evenly. The frequency in a spring mass system does not alter with energy, but the amplitude does. In other words, atomic oscillations have the same frequency but a greater amplitude. In other words, the atoms move farther throughout their oscillations. The amplitude may rise to a point where the spring-ey linkages begin to break and the lattice collapses if you provide them with enough energy. To put it simply once again, the solid dissolves.
