Answer» The solids are characterized by incompressibility, rigidity and mechanical strength. The molecules, atoms or ions in solids are closely packed, i.e., they are held together by strong forces and cannot move about atrandom. Thus solids have definite volume, shape, slow diffusion, low vapour pressure and possess the unique property of being rigid. Such solids are known as true solids.E.g. NaCl, KCL, Sugar, Ag, Cu, etc.On the other hand the solid which loses shape on long standing, flows under its own weight and is easily distorted by even mild distortion force is called pseudo solid e. g. glass, pith etc. |
