WHY SOLIDS HAVE ONLY VIBRATORY MOTION
Asked by akashleena chakrabarti | 12 Apr, 2013, 09:42: PM
Expert Answer
In the solid, the particles are touching, and the only motion allowed to them is vibration. The particles may be arranged regularly (in which case, the solid is crystalline), or at random (giving waxy solids like candles or some forms of polythene, for example).
The particles are held in the solid by forces which depend on the actual substance - ionic bonds, covalent bonds, metallic bonds, hydrogen bonds or van der Waals attractions.
