Title: What is Chemistry?


1
What is Chemistry?
  • The study of matter, its composition,
    properties, and the changes it undergoes.
  • Applied Chemistry - uses chemistry to attain
    certain goals, in fields like medicine,
    agriculture, and manufacturing
  • Pure chemistry - gathers knowledge for the sake
    of knowledge

2
5 Major Areas of Chemistry
  • Analytical Chemistry - concerned with the
    composition of substances.
  • Inorganic Chemistry - deals with substances
    without carbon
  • Organic Chemistry - deals with substances
    containing carbon
  • Biochemistry - chemistry of living things
  • Physical Chemistry - deals with the physical
    properties of substances

3
Chemistry
  • important to all sciences - biology, geology,
    physics, engineering, etc.
  • a language with its own vocabulary.

4
Why Study Chemistry?
  • everyone and everything around us involves
    chemistry
  • possible career for your future

5
Chemistry Far and Wide
  • Materials - perfume, steel, ceramics, plastics,
    rubber, paints, nonstick cooking utensils,
    polyester fibers
  • Energy - fossil fuels, solar, batteries, nuclear
    (dont forget pollution!)

6
Chemistry Far and Wide
  • Medicine and Biotechnology-
  • vitamin C, penicillin, aspirin
  • materials for artery transplants and hipbones
  • Human Genome Project
  • bacteria producing insulin
  • cloning

7
Chemistry Far and Wide
  • Agriculture - worlds food supply
  • plant growth hormones
  • ways to protect crops
  • disease resistant plants
  • The Environment- both risks and benefits involved
    in discoveries
  • carbon dioxide, ozone, warming

8
Chemistry Far and Wide
  • Astronomy and Space Exploration-
  • composition of the planets
  • analyze moon rocks
  • planet atmospheres
  • life on other planets?
