chemistry
the study of the composition, structure, and properties of matter, the process that matter undergoes, and the energy changes that accompany these processes
organic chemistry
the study of all chemicals containing carbon compounds
inorganic chemistry
the study of non-organic substances, many of which have organic fragments bonded to metals
physical chemistry
the study of the properties and changes of matter and their relation to energy
analytical chemistry
the identification of the components and composition of materials
biochemistry
the study of substances and process occurring in living things
theoretical chemistry
the use of mathematics and computers to understand the principles behind observed chemical behavior and to design and predict the properties of new compounds
chemical
any substance that has a definite composition
volume
the amount of three dimensional space an object occupies
mass
the amount of matter in an object
matter
Anything that has mass and takes up space
atom
the smallest unit of an element that maintains the properties of that element
element
A pure substance that cannot be broken down into other substances by chemical or physical means
compound
a substance that can be broken down into simple substances
pure substance
has a fixed composition
homogeneous
cannot see different parts
Heterozygous
can see different parts
filtration
can be used to separate larger solid particles in a mixture of solid and liquid substances
Chromatography
takes advantage of the physical property of affinity of individual substances to different lab tools or paper or liquid solvent
distilation
process where a mixture is heated and substances are separated based on boiling points
physical property
A characteristic of a pure substance that can be observed without changing it into another substance
intensive property
a physical property that remains the same no matter how much of a substance is present
extensive property
a physical property that depends on the amount of matter present
mechanical energy
comes from position or motion (pressure)
radiant energy
comes from electromagnetic waves such as visible light and microwaves
nuclear energy
comes from within atoms
