Chapter T wo: Measurement, Problem Solving, and the Mole Concept Thursday, September 1, 2016 8:40 PM 2.1: "The Metric Mix-Up: A $125 Million Unit Error" Basically a mars weather monitor failed because they mixed up units. Units are critical 2.2: "The Reliability of Measurement" Reliability depends on the instrument used to measure More digits in measurement = more reliability o Scientists do this on purpose to reflect reliability of instrument o Uncertainty is in the last recorded digit (+/- 1) Accuracy: how close the measured value is to the actual value Precision: how close the measured values are to each other or how reproducible they are Random Error: error that has equal probability of being too high or low o Averages out with repeated trials Systematic error: tends to be either too high or too low o Doesn't average out. 2.3: "Density" Density of a substance is the ratio of its mass to its volume (density=mass/volume) o A physical property of a substance o Depends on the temperature of the substance o An intensive property: independent of the amount of the substance Mass, for example, in an extensive property (depends on the amount of the substance. Only knowing something's mass doesn't identify it.) 2.4: "Energy and Its Units" Two fundamental components of our universe are matter and energy Energy: the capacity to do work o Work: th
