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.
