A cylindrical container is to be made from certain solid material which the following constraints : It has a fixed inner volume of V mm^3 , has a 2 mm thick solid wall and is open at the top. The bottom of the container is a solid circular disc of thickness 2 mm and is of radius equal to the outer radius of the container. If the volume of the materia! used to make the container is minimum when the inner radius of the container is 10 mm, then the value of V/(250pi) is

In an ideal crystal, the entropy of the constituents at absolute zero temperature (0K) is zero. However, the crystals generally suffer from certain defects also called imperfections They may be both electronic and atomic in nature. The atomic imperfections may be stoichiometric (Schottky and Frenkel defects) or non-stoichiometric (metal excees and metal deficiency defects). In addition to these, there are impurity defects which are caused by the addition of certain impurities of metals and this is known as dopping. The dopping leads to semi conductors which may be either n-type or p-type in nature. In stoichiometric defects, the ratio of positive and negative ions as indicated by chemical formula of the compound:
