WebSolids Solids are the chemical substances which are characterised by define shape and volume, rigidity, high density, low compressibility. The constituent particles (atoms, molecules or ions) are closely packed and held together by strong interparticle forces Types of Solids The solids are of two types : Crystalline solids and amorphous solids. WebMolecular solids are solids formed from individual molecules attracting each other based on intermolecular forces like London dispersion, dipole-dipole, and hydrogen bonding. Molecular solids generally have low melting points with water at 0°C being a good example.
