Abstract:
|
Systematic errors can cause measurements to deviate from the actual value of the quantity being measured. Using a meterstick that is not marked off correctly, using a balance to measure mass that has not been properly zeroed, or misinterpreting the range of a voltmeter are all examples. A simple Boyle's law experiment seeks to show that the pressure of a gas multiplied by its volume is a constant. A first attempt results in an experimental difference of about 5%. However, when the proper volume is taken into account, the difference reduces to about 1%. A discussion of how to measure the correct volume by indirect methods is presented.
