1. What is Volume
Volume is defined as the amount of space taken up by a three-dimensional object.

2. Volume often refers to liquid volume, which is defined as the amount of space taken up by a liquid, which spreads completely to fill its container.

4. Volume of Liquids Reading a Meniscus

6. Measuring Volume by Displacement
Used for irregular shaped objects
Select a graduated cylinder large enough to put the object in
Add water - at least 10 mL and record accurately

7. SLOWLY add the object to be measured:
rubber stopper
slug
metal cylinder
Read the new level of the water
The water will rise an amount equal to the volume of the object

8. What not to do

9. Here’s what the cylinder should look like

10. Do the math 1 . Original reading of volume Final volume of water
This will equal the volume of the object
22.5 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 AM
Value of Error in Minting Pennies
How close the individual volumes are to each other 
Calculate as follows
% error = average volume - actual volume    
      actual volume
% error = error in minting the pennies
The 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 pennies 13

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.
