This has to do with the consistency or reproducibility of a measurement and is closely related to a measurement's uncertainty
precision
the chemistry of living things
biochemistry
In this, the scientist deliberately makes certain changes in the world around him and observes the consequences
experiment
To convert 6.87 x 10-2 to ordinary notation, the decimal point would move in this direction
left
Giving up a characteristic that is less important for one that is more important
tradeoff
To perform unit conversions, you should use this technique in which the value of a conversion factor should always equal one
dimensional analysis
Analyzes many kinds of substances taken from a crime scene
Forensic chemists
A factor that is observed or measured to determine the results of an experiment
dependent variable
Numbers obtained by counting are usually this
certain
A model of the design that is used for testing
prototype
This branch of science deals with the study of the composition, structure, and properties of matter and with the changes that matter undergoes
chemistry
Foundational to the other areas of chemistry
physical chemistry
The ability of other scientists to reach the same conclusion by performing the same experiment under different conditions and by performing other experiments to test the same hypothesis
reproducibility
This limitation is limited to the study of created matter and energy in the present and prevents the study of origins from being true science
Scope of science
The minimum characteristics that a design must have to function at all
criteria
A general explanation of why some part of the universe behaves the way it does
theory
study substances that are compounds of carbon
organic chemistry
Factors that remain the same in all groups
controlled variables
What value does the prefix centi- represent?
10-2
When defining the problem, the engineer needs to identify these two things
criteria constraints
On this principle, scientists base the assumption that events in the universe have rational causes
principle of causality
Deals with identifying what substances are present in materials and how much of each substance is present
analytical chemistry
A group in which the independent variable is absent
control group
The average of a series of measurements should not have more of these than the measured values
significant digits
After researching and developing design ideas based on criteria and constraints, this would be the next step
Choose a design idea based on the criteria and constraints
