Why material in solid state are crystalline
Most of the materials in solid state are crystalline. Between these many are in the polycrystalline state. To get single crystal one has to employ a suitable crystal growth process. This may differ from one material to another. To understand the dissimilar material properties, the structure of the material is very important. The unit cell which is the building block of a crystalline material can be made of the basic units namely the basis or the pattern unit or the motif.
Explain Buoyancy in Air The same buoyancy happens in air. This is how hot air balloons fly. By heating the air and lowering the density of the air in the balloon, the balloon f
