Four Basic Phases of Chemistry

Four Basic Phases of ChemistryIn chemistry, the most important of the four phases is the solid phase. Solidification occurs when a substance starts to cool and solidifies in its form of a solid. The four phases in this phase include solidified, semi-solid, liquid and gas.The solid phase in chemistry is a phase in which the substance is solid at room temperature but liquefies at high temperatures. There are several methods of solidification. One of the more popular forms of solidification involves the use of low temperatures and low pressures to rapidly freeze a solution.Another form of solidification that occurs at low temperatures is the stable gas phase. This phase occurs when an impurity is stabilized in its form of a solid. It is usually stable because it is not likely to spontaneously decompose into liquid and gas when exposed to oxygen. If an impurity is stabilized in solid form, it can also be stored as a solid so that it does not decompose and form liquid or gas.Solidificatio n can occur in any material, such as metals, liquids and gases. These materials contain some kind of solidification process. As the solid phase reacts with another substance, the solid phase interacts with the material. The reaction can happen spontaneously or it can result from thermal or electrical heating.There are many different solidification reactions in which the solid phase will react with a solid or a liquid. Some of these include the formation of complex molecules such as oxygenated hydrocarbons, the formation of solid, highly crystalline silica, formation of liquid crystals, solidification of alkaline materials, formation of solid carbonates, formation of partially solid phosphates, crystallization of phenolic compounds, and solidification of hydrogen sulfide. These different reactions can occur between a liquid and a solid or between a solid and a gas.The solubility of solutes in solid phase can be a major problem when they are involved in a chemical reaction. For exampl e, if an acid or a base reacts with a solid, they tend to form crystals and then clump together resulting in a huge precipitation. The precipitation of the solid phase can affect the reaction, since it prevents the complete reaction of the solid to the gas phase.Solidification involves the settling of the substance into a solid that is slightly less dense than the surrounding medium. This process can be used for minerals, natural gas, and crude oil.
