What is Chemistry?
the study of matter
and its changes
Areas of Chemistry
• Organic
• Inorganic
The study of most carbon-containing compounds
The study of all substances not classified as organic,
mainly those compounds that do not contain carbon
• Analytical
The identification of the components and composition
of materials
• Physical
The study of the properties, changes, and relationships
between energy and matter
• Biochemistry
The study of substances and processes occurring in
living things
Areas of Chemistry
organic
the study of carboncontaining
compounds
inorganic
everything except
carbon
e.g., compounds
containing metals
physical
measuring physical
properties of
substances
e.g., the melting
point of gold
biochemistry
the chemistry of
living things
