DEFINITION OF CHEMISTRY? ARE YOU SEARCHING FOR THE BEST DEFINITION OF CHEMISTRY EVER, ARE YOU PLANNING ON WRITING A REPORT OR YOU ARE JUST TRYING TO GET SOME ASSIGNMENT DONE! WHAT EVER YOUR REASON IS FOR BUMPING INTO THIS ARTICLE, WE HOPE YOU THIS ARTICLE ANSWER YOUR QUESTION AND CLEAR ALL YOUR DOUBT.
Chemistry as a core subject that deal on 5
basic composition/concept. Chemistry is divided into fivebranch which include:
Inorganic chemistry studies materials such as metals and gases that do not have
carbon as part of their makeup.
uses both qualitative and quantitative analysis to
identify measure the physical and chemical properties of substances.
Physical chemists study how matter and
energyinteract. Example of are Thermodynamics and quantum mechanics.
the study of chemical processes that occur within living organisms.
studies compounds that contain the element carbon. Carbon has many unique properties that allow it to
form complex chemical bonds and very large molecules. Example of organic
chemistry is petroleum chemistry and chemistry of hydrocarbon.
Most secondary and primary institution chemistry
is focused on the hydrocarbons and its family, petroleum chemistry andthe physical
aspect of chemistry which include: Atoms, molecules ions e.t.c.
WHO IS A CHEMIST AND WHAT DOES A CHEMIST
Who is a chemist?
According to careerexplorer, Chemist are scientist who researches chemical substances, performs experiments with the use of chemical substances, measures the effects of chemical compounds in various situations, and studies inter-chemical reactions.
A chemist also work to improve the quality of established chemical products and utilizes advanced computer programs to establish new technologies in the field.
are also scientists who study the makeup of substances and the changes that
they undergo. He/she tests for various ways to make
existing products better and develops new products.
Examples of product a chemist analysed includehousehold cleaners,
pharmaceutical drugs, plastics, and several other products may be improved by a
Chemists analyse and test substances to
find out their composition and concentration of elements. They may also write
technical reports that would detail methods and results of their research. A chemist often work as
part of a larger research team in order to create much needed compounds for use
in a wide variety of practical applications.
What does a chemist do?
ON our day to day activities, we make
use of the word chemist, sometimes we go as much to name anyone we see carrying
chemical as a chemist without having a view of who a chemist is and what a
Chemists measure the physical properties of substances. They may
take new compounds and measure the melting points and boiling points. They may
measure the strength of a new polymer strand or determine the octane rating of
a new gasoline.
Chemists analyze substances. They determine the content of a substance, how much of
something is in a substance, or both. They analyze solids, liquids, and
gases. They may try to find the active compound in a substance found in
nature, or they may analyze water to see how much lead is present.
Chemists create, or synthesize, new
substances. They may try to make the
synthetic version of a substance found in nature, or they may create an
entirely new and unique compound. They may try to find a way to synthesize
insulin. They may create a new plastic, pill, or paint. Or they may try to
find a new, more efficient process to use for the production of an
Chemists create models and test the
predictive power of theories. This area
of chemistry is referred to as theoretical chemistry. Chemists who work in
this branch of chemistry use computers to model chemical systems. Theirs
is the world of mathematics and computers.
WHAT IS CHEMISTRY: DEFINITIONS OF CHEMISTRY
Definition of chemistry 1.
Chemistry is the science that systematically studies the
composition, properties, and activity of organic and inorganic substances and
various elementary forms of matter.
Definition of chemistry 2
Chemistry is the “scientific study of
matter, its properties, and interactions with other matter and with
of chemistry 3
Chemistry is the branch of science
concerned with the substances of which matter is composed, the investigation of
their properties and reactions, and the use of such reactions to form new
Definition of chemistry 4
Chemistry is the scientific discipline
involved with elements and compounds composed of atoms, molecules and ions:
their composition, structure, properties, behaviour and the changes they
undergo during a reaction with other substances.
Definition of chemistry 5
Chemistry is a branch of natural science
that deals principally with the properties of substances, the changes they
undergo, and the natural laws that describe these changes.
Definition of chemistry 6
Chemistry is a branch of science that
deals with the properties, composition, and structure of substances, the
transformations they undergo, and the energy that is released.
Definition of chemistry 7
Chemistry also is concerned with the
utilization of natural substances and the creation of artificialones.
IMPORTANT OF CHEMISTRY
Medicine: You need to
understand basic chemistry so you can understand how vitamins,
supplements, and drugs can help or harm you. Part of the importance of
chemistry lies in developing and testing new medical treatments and
explains how food changes as you cook it, how it rots, how to preserve
food, how your body uses the food you eat, and how ingredients interact to
Environmental Issues: Chemistry is
at the heart of environmental
issues. What makes
one chemical a nutrient and another chemical a pollutant? How can you
clean up the environment? What processes can produce the things you need
without harming the environment?
Cleaning: Part of the importance of chemistry is it explains how
cleaning works. You use chemistry to help decide what cleaner is best for
dishes, laundry, yourself, and your home. You use chemistry when you use
bleaches and disinfectants, even ordinary soap and water. How do they
work? That’s chemistry.
Fermentation: without chemistry, fermentation and the breaking down of compounds
such as carbohydrate into simple sugar might not be totally possible.
glass making: glass is a commodity that is found in every
house today in the world. The manufacturing of glass might not be possible
Formation of books: the production of products such as book are purely from chemical process. Books are form from wood and trees, with the addition of chemicals that help decaying.
