Role_of_Chemistry_in_Growing_World_Population

ROLE OF CHEMISTRY IN GROWING WORLD POPULATION Chemistry is the science[->0] of matter[->1], especially its properties, structure, composition, behavior, reactions[->2], interactions and the changes it undergoes.Chemistry is sometimes called "the central science[->3]" because it connects physics with other natural sciences[->4] such as astronomy[->5], geology and biology.Physics also studies matter, but physics is the science of quantities of space and matter, and laws governing them. Chemistry is a branch of physical science[->6] but not a branch of physics.However, chemistry utilizes physics[->7]. For example, chemistry uses quantities like energy[->8] and entropy[->9] in relation to the spontaneity[->10] of chemical processes[->11]. It also explains the structure and properties of matter as a consequence of the physical properties of chemical substances and their interactions. For example, steel[->12] is harder[->13] than iron because its atoms are bound together in a more rigid crystalline lattice[->14]; wood burns or undergoes rapid oxidation[->15] because it can react spontaneously with oxygen[->16] in a chemical reaction[->17] above a certain temperature[->18]; sugar and salt dissolve in water because their molecular/ionic properties are such that dissolution is preferred under the ambient conditions;The etymology of the word chemistry has been much disputed. The genesis of chemistry can be traced to certain practices, known as alchemy[->19], which had been practiced for several millennia[->20] in various parts of the world, particularly the Middle East. The Role Of Chemistry To Our Society Chemistry plays a huge and important role in society, with relation to shelter and clothing. For example, chemists come up with new paints and epoxy sprays that protect shelters from the wear and tear inflicted by rain, wind, sun and pollution. These space age coatings and paints are designed to make properties look better, perform better and last longer. Thermal chemical compounds may protect rooftops and also help structures stay at the right temperature. These chemical compounds have been proven to reduce energy costs and to create a more comfortable shelter for use as a private residence, business headquarters, or any other purpose. Chemical engineers who create fabrics that offer special, stain-resistant properties are also designing technologically advanced fabrics that come out of the dryer without wrinkles or creases. These new fabrics are reducing the amount of time it takes to care for clothes; they are also helping the environment by making it easier for people to avoid dry-cleaning and other, energy-wasting cleaning methods. Today, chemical technology is revolutionizing the way people wear and take care of clothing. Today's fabrics can be treated for specific purposes, such as rugged outdoor use, or business wear. Each fabric can be chosen based on its aesthetic appeal, as well as its special chemical properties. Stain-resistant fabrics contain a coating that will: • Allow liquids, such as coffee or red wine, to "roll off" of the surface • Make them easier to clean, in the event that a stain does transfer onto fabric Chemists spend years learning how to combine chemicals to obtain a positive end result. Lab work, analysis, and experiments are used to make technological advancements that benefit mankind and contribute to better shelter and clothing. Chemists are a vital part of society, and they improve our living conditions with their achievements and innovative thinking.
