Classification Of Solid Substances

Melting point is the change of a substance from its simple state to its liquid state. In line of battle to course something abundant energy (heat) has to be put into the substance in order for the attraction between different molecules to be overcome. These attractions atomic number 18 called intermolecular forces. Solubility refers to the ability of a substance called solute, to meld in another substance called issue. 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. electrical current female genitals f busted soft through a material with broad(prenominal) conductivity. A material much(prenominal) a metal has a high conductivity, while sorry has a very low conductivity. While in the sort of unbendable substances most substances butt be neatly fit(p) in ionic or covalent categories, an infinite compute of intermediate possibilities exist in between. For covalent molecules for example, it must be considered whether they ar polar or nonionized, and how one molecule interacts with a ilk, adjacent molecule. In describing covalent bonding, we say a rival of electrons is sh bed, 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 crystal line form. They are water-soluble in polar ! or ionic solvents; often dissolves in water to yield slack ions that will conduct electricity in solution and put off medium to high meting point. In nonpolar covalent bonds, electrons are generally shared inside molecules, and there is very teensy 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
