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...
