10 Do the math 1 . Original reading of volume Final volume of water This will equal the volume of the object22.5 mL mL = 5.1 mL Therefore, the volume of the object by displacement is 5.1 mL
11 A penny is a flat cylinder – could calculate the volume by direct measurement.
12 Value of Error in Minting Pennies 4/7/2017 4:12 AMValue of Error in Minting PenniesHow close the individual volumes are to each other Calculate as follows% error = average volume - actual volume actual volume% error = error in minting the penniesThe smaller the %error, the better the precision in making of the pennies.12
13 Example: % error in minting pennies = average volume - actual volume % error in minting pennies = 1.2g g g= X 100%= 14 %So there is a 14% error in minting of these particular pennies13
14 When are Equal Volumes Not Equal? 100mL 250mL 250 mL
15 Procedure Measure level of water as each “equivalent volume” is added. Ruler“equivalent volume”Measure level of water as each “equivalent volume” is added.
