Classification Of Solid Substances

Melting point is the change of a substance from its frank state to its liquid state. In line of battle to melting something abundant energy (heat) has to be put into the substance in order for the attraction between different molecules to be overcome. These attractions ar called intermolecular forces. Solubility refers to the ability of a substance called solute, to ignore in another substance called solvent. 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. electric current female genitals f busted slowly through a material with broad(prenominal) conductivity. A material much(prenominal) a metal has a high conductivity, while preventive has a very low conductivity. While in the miscellany of good substances most substances butt be neatly displace in ionic or covalent categories, an infinite subdue of intermediate possibilities exist in between. For covalent molecules for example, it must be considered whether they be polar or nonionised, and how one molecule interacts with a ilk, adjacent molecule. In describing covalent bonding, we say a touch 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 crystalline form. They are water-soluble in polar or i! onic solvents; often dissolves in water to yield set down ions that will conduct electricity in solution and organize medium to high meting point. In nonpolar covalent bonds, electrons are generally shared inside molecules, and there is very particular 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
