Document Summary
Degrees f = degrees c(9/5) + 32. Accuracy: how close the measure value is to the actual value. Systematic error: always affects measurements the same amount or by the same proportion; predictable. Caused by observational error, imperfect instrument calibration, or environmental interference. Ex: forgetting to tare a balance will always produce measurements that are off by the same amount. Precision: how close a set of measurements are to one another. Random error: causes one measurement to differ slightly from the next. Caused by limitations of instruments, environmental factors, or slight variations in procedure. Ex: when reading the volume from a ask, you read it from a different angle each time. Intensive: independent of the amount of the substance. Extensive: depends on the amount of the substance. Work: the action of a force through a distance. Systems w/ high pe tend to change in a way that lowers their pe so that they are stable.
