Essential concept to crack IIT-JEE


This topic helps students to prepare in right direction that are required to take on the JEE Main +     Advanced. essential for JEE Main & Advanced Exam preparation.  The solids are the substance which have definite volume and definite size. The intermolecular distances in solids are short and intermolecular forces are strong. Solids are almost imcompressible.The study of properties and structure of solids is important subject for the scientists.
