Making CBSE notes are highly imperative in Class 12th chemistry, as it has very vast syllabus and concept coverage. Studying NCERT solutions for Class 12th chemistry is not sufficient enough to build concepts if the preparation is not comprehensive. The CBSE syllabus can become very difficult if students’ preparations are confined to CBSE notes without conceptual understanding. Solid State in Chemistry Class 12th is an important concept when accounted for the weightage of marks that it holds. With Extramarks learning solutions, every concept is explained with minute detail along with audio-visuals and pictorial representation. Like other learning solutions from Extramarks, its complete chapter is composed as per the title and sub title of Class 12th NCERT Chemistry book. As evident from the concept, the three states of matter are solid, liquid & gas. Amongst all these states, liquid and gases are considered fluids because of their ability of free flow which solids are incapable of. In contrast with liquids and gases, there is a strong intermolecular force of attraction between the particles in solid. The solids are constituted of particles in fixed position that can only oscillate about their mean position. This gives the solids the rigidity and therefore a fixed shape. Therefore, solid state of matter possesses fixed mass, volume, shape and rigidity. In Extramarks learning solutions teaching solid state in Chemistry Class 12th, videos based explanation, along with CBSE notes, show how constituent particles of solids are arranged. Extramarks learning solutions pictorially describe how specific arrangements cause wide range of properties and like superconductors, magnetic materials, polymers etc.
