What is the definition of chemistry?
Chemistry is a branch of science concerned with the study of matter and the chemicals that make up that matter. It also covers the characteristics of these chemicals as well as the processes that occur when they combine to generate new compounds. Chemistry is largely concerned with atoms, ions, and molecules, all of which combine to form elements and compounds. Chemical bonds are the most common way for these chemical entities to react. It's worth noting that the interactions between matter and energy are also investigated in chemistry.
Organic Chemistry
Organic chemistry is one of the most significant fields of chemistry, and it deals with chemical molecules that contain carbon atoms and 'carbon-hydrogen' bonds (hydrocarbons). The 'Chemistry of Life' is a branch of chemistry that studies the structure, characteristics, and reactivity of organic molecules. Organic chemistry teaches students how to recognize and classify naturally occurring chemicals as well as how to synthesize molecules with desired characteristics and functionalities. Pharmaceuticals, gasoline, rubber, cosmetics, plastic, detergents, agrochemicals, and coatings are just a few of the areas where graduates can work.
Noncarbon chemical substances, or those that do not include carbon-hydrogen bonds, are studied in inorganic chemistry, which focuses on their structure, characteristics, and reactions. In other words, it is a discipline of chemistry that deals with 'non-organic' substances found in nature. The creation and behavior of inorganic or organometallic chemical compounds present in the earth's crust and non-living materials are covered in this course.
Physical chemistry is concerned with the 'physical qualities' of chemical compounds as determined by laws and numerous physics concepts such as motion, energy, force, time, statistical mechanics, quantum chemistry, and thermodynamics. Temperature, volume, pressure, conductivity, plasticity, strength, surface tension in liquids, solubility, viscosity, boiling point, melting point, and color are just a few of the physical properties of chemical compounds that students may learn about in this intriguing subject of chemistry. Various mathematical models and formulae are used to study the issue.
Analytical chemistry is a field of chemistry concerned with the 'identification, classification, and characterization' of chemical compounds. Chemists and scientists can use Analytical Chemistry to estimate the concentration of chemical compounds in a particular sample. The following two categories have been assigned to the subject:
Qualitative analysis: It entails procedures for determining the presence of a chemical compound in a sample.
Quantitative analysis: It entails determining the substance's concentration or quantity in each sample.
Biochemistry
Biochemistry regarded as one of the most significant fields of chemistry, investigates biological structure, composition, and chemical interactions at the cellular and molecular levels. Plants, insects, viruses, bacteria, and other biological creatures are included. Biology is combined with Organic, Inorganic, and Physical Chemistry to form Biochemistry. Diseases, the molecular foundation of heredity, and how living organisms acquire energy from food are just a few of the subjects addressed in this course.
Environmental Chemistry
It's the science of biochemical processes occurring in the natural world. Environmental chemistry is a fusion of several disciplines such as biology, mathematics, and toxicology that seeks to identify pathways for long-term development. Because it deals with environmental functions, environment chemistry is an important field of chemistry.
Manufacturing new goods involves the use of industrial chemistry. To create a new product, raw materials are dissolved, heated, filtered, and other procedures are used. Petrochemicals such as ethylene, propylene, benzene, and styrene, as well as ceramic products such as silica brick and frit, are examples of industrial chemistry.
It is mostly concerned with polymers and macromolecules. Organic chemistry, analytical chemistry, and physical chemistry all have polymer structures. It's also possible to include it into nanotechnology. Thermoplastics, thermosets, elastomers, and synthetic fibers are the several types of thermoplastics.
Nuclear Chemistry
It is the study of nuclear reactions, as the name suggests. It is widely utilised in a wide range of treatments and cures. Radioactivity, nuclear processes, and transformations are all discussed.
The study of Earth Systems and Environmental Sciences is known as geochemistry. Understanding the mineral, weathering agents, and other environmental issues requires geochemistry. Geochemistry is the study of all the chemical reactions that occur on the surface of the Earth.
