Question

why do the molecules in a solid vibrate about their positions?​

Answer 1

Answer:

answer is below hope it helps if it does please mark it as brainliest ❤️

Explanation:

The particles in a solid are held in a fixed position by bonds. This can be a lattice or it can be a more random arrangement of particles. Either way, they are fixed.

The particles vibrate about their fixed position but they are always attached to the same neighbours. As the solid gets hotter, the particles vibrate more vigorously until some of the bonds start to break. At this point, the solid begins to melt. Its temperature stops going up because the energy is being used to break the bonds rather than make the particles vibrate more.

Answer 2

in solid molecules is vibrate in its mean position due to transfer of heat .
