8D.5 Flashcards
what is random error
this is an error caused by unpredictable changes in conditions such as temperature or pressure, for by a diff in the recording that is difficult to get exactly right
what is a systematic error
it is because of an apparatus, and either leads to a recording being too high or too low
what is a measurement uncertainty
it is a potential error that is always involved when using a piece of apparatus to make a measurement
the measurement uncertainty is measured by
the precision of the apparatus
what are the capacity and the measurement uncertainty in the burette
capacity 50 cm, and Mu of 0.05 but since its read twice 0.10
what are the capacity and the measurement uncertainty in the pipette
capacity 25 Mu of 0.06
what are the capacity and the measurement uncertainty in the volumetric flask
capacity 250 Mu of 0.3
