Classification Of Solid Substances

Melting point is the change of a substance from its candid state to its liquid state. In line of battle to ladder something abundant energy (heat) has to be put into the substance in order for the attraction between different molecules to be overcome. These attractions argon called intermolecular forces. Solubility refers to the ability of a substance called solute, to discount in another substance called root. A mixture of solute and solvent forms a homogeneous solution of the solute in the solvent. Sugar for example, dissolves in piddle to make a homogenous solution. Conductivity defines a cloths ability to conduct electrical energy. voltaic current female genitals f busted well through a material with broad(prenominal) conductivity. A material such a metal has a high conductivity, while sorry has a very low conductivity. While in the miscellanea of comforting substances most substances butt be neatly position in ionic or covalent categories, an infinite descend of intermediate possibilities exist in between. For covalent molecules for example, it must be considered whether they ar polar or unionised, and how one molecule interacts with a homogeneous, adjacent molecule. In describing covalent bonding, we say a couple on of electrons is sh ard, while in ionic bonding electrons are transferred.

To summarize, solid substances can be classified ad as ionic, nonpolar covalent, polar covalent, network covalent and metallic. In ionic compounds electrons are transferred and ions of opposite charge are attracted to each(prenominal) other to form solids in crystallin e form. They are water-soluble in polar or ! ionic solvents; often dissolves in water to yield absolve ions that will conduct electricity in solution and ca-ca medium to high meting point. In nonpolar covalent bonds, electrons are generally shared inside molecules, and there is very weeny interaction between molecules. They have low melting point. These materials are frequently gases or liquids, insoluble in polar solvents like water, and soluble in polar solvents like...If you want to get a full essay, order it on our website: OrderCustomPaper.com
