This SlideShare is all about "What is Chemistry?", "What are the Branches of Chemistry?", its definitions and examples.

2. 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.

4. Physical chemistry is the study of
macroscopic and microscopic
phenomena in chemical systems in
terms of the principles, practices, and
concepts of physics such as motion,
energy, force, time, thermodynamics,
quantum chemistry, statistical
mechanics, analytical dynamics and
chemical equilibria.

5. Physical chemists aim to develop a
fundamental understanding at the molecular
and atomic level of how materials behave
and how chemical reactions occur,
knowledge that is relevant in nearly every
area of chemistry.
Some of the major examples of physical
chemistry are thermochemistry, which
includes the study of heat energy of chemical
reactions taking place during phase
transitions like gas to liquid or vice versa. It
tells us about entropy, heat capacity, Gibbs
free energy, or heat of formations.

6. Organic chemistry is a sub discipline
within chemistry involving the
scientific study of the structure,
properties, and reactions of organic
compounds and organic materials, i.e.,
matter in its various forms that contain
carbon atoms. Study of structure
determines their structural formula.

7. It focuses on the study of the structure,
properties, composition, reactions, and
preparation of carbon-containing
compounds.
They're central to economic growth, and
are foundational to the fields of
biochemistry, biotechnology, and
medicine. Examples of where you can
find organic compounds
include agrichemicals, coatings,
cosmetics, detergent, dyestuff, food, fuel,
petrochemicals, pharmaceuticals,
plastics, and rubber.

8. Inorganic chemistry
is concerned with the
properties and behavior of
inorganic compounds, which
include metals, minerals, and
organometallic compounds.
Table salt or sodium chloride.
Carbon dioxide.
Diamond (pure carbon)
Silver.
Sulfur.
Oxides.
Sulfates.
Phosphates.

9. Analytical chemistry
studies and uses
instruments and
methods to separate,
identify, and quantify
matter.
In practice, separation,
identification or
quantification may
constitute the entire
analysis or be combined
with another method.
Separation isolates
analytes.
Analytical chemistry plays
an enormous role in our
society, such as in drug
manufacturing, process
control in industry,
environmental monitoring,
medical diagnostics, food
production, and forensic
surveys. It is also of great
importance in different
research areas.

10. Biochemistry or biological chemistry is the
study of chemical processes within and relating
to living organisms. A sub-discipline of both
chemistry and biology, biochemistry may be
divided into three fields: structural biology,
enzymology, and metabolism.
Photsynthesis is an example of biochemistry.
This is a chemical process by which plants
convert sunlight into food. Another example is
the effect of the drug caffeine on the human
nervous system. This process involves a
number of complex biochemical reactions.
