|
== Definitions ==
|
|
|
|
* Chemistry
|
|
- Study of the compostion, structure, properties and reactions of matter
|
|
* [[matter|Matter]]
|
|
- Any material that occupies space and has mass
|
|
* Composition
|
|
- Identity and relative amounts of the components of matter. Described with
|
|
"formulas"
|
|
* Macroscopic
|
|
- Large scale properties that may be determined directly
|
|
* Microscopic
|
|
- Small scale properties that must be determined by indirect methods. Usually
|
|
on the atomic or molecular level
|
|
|
|
== [[energy|Energy]] ==
|
|
|
|
Ability to do work
|
|
|
|
see [[energy]]
|
|
|
|
== Scientific Method ==
|
|
|
|
Way to thourghly understand the world that is testable
|
|
|
|
== Accuracy vs Precision ==
|
|
|
|
* Accuracy
|
|
- agreement of measured values with the "correct" values
|
|
* Precision
|
|
- how reproducable is the measurment
|
|
|
|
== Error ==
|
|
|
|
* Systematic
|
|
- Error is higher/lower than expectation, usually due to measurment device
|
|
* Random error
|
|
- Always present, makes values change slightly
|
