ABOUT THE ABOVE Everyone knows that chemistry is big. But, does anyone know exactly what it means? An easy way to become familiar with the field is by downloading this PDF of the modern abc chemistry class 12, written by someone who obviously has experience with the subject. The author has broken down topics into easy-to-understand subheads and includes accompanying graphs and pictures. This article is written in a way that anyone can understand it and use it. What is the definition of chemistry? Chemistry is the study of matter; its properties, composition, structure, reactions, and how it changes over time. It also studies the interactions and transformations that matter undergoes. Wondering what exactly chemistry entails? If you think of a number of chemical reactions you can probably figure out on your own what atoms and molecules are. Atoms form molecules which form compounds. Keep in mind that these compounds interact with each other and undergo chemical reactions to produce more complex substances or substances with different physical properties than the original molecule or compound was composed of. There are also some specific compounds called bioactive compounds that do things like kill bacteria and fungi and even inhibit the growth of cancer cells. Chemistry is a broad and vast field that is influenced by the sciences of physics, math, and biology. Chemistry determines what all those numbers on your bathroom scale mean, as well as many other things such as how you can make a new compound such as sugar from carbon dioxide or protein from amino acids through chemical reactions or how you can use one particular type of molecule to make another different type. It studies the way materials change over time due to chemical reactions that often take place due to either heat or light or a combination of both. For example, when iron rusts (or oxidizes) it changes into the compound of iron oxide. This is what makes your bathroom faucet or garden gate rusty. What are some of the definitions of chemistry? The exact meanings of chemistry are different for each person who uses them, but here are some general terms that cover most everyone's definition of the subject. Chemistry encompasses many different areas including industrial, pharmaceutical, biochemistry, food technology, environmental toxicology and more. Chemicals : Structured substances composed of atoms with particular properties that can be combined in ways that produce new materials . These chemicals and materials can be natural and non-biological (inorganic) or organic (carbon-based) and can be found all around you. Examples include salts, gases, and plastics. Chemistry is very useful for understanding the behavior of these substances and has implications in a number of fields such as medicine, technology, agriculture , as well as many more. Biochemistry : The study of living things on an atomic level . This subject differs from chemistry because it focuses on how molecules interact rather than atoms or compounds on their own. Biochemistry is used to find out about properties of living things such as the healing properties of plants and how disease occurs and spreads inside the body. cfa1e77820
