Volume
The amount of space an object takes up. (think of it as how big an object may be).
We measure it with…
Beaker(Kind of Accurate)
GraduatedCylinder(Very Accurate)

Volume of Liquids
• Always use a graduated cylinder to measure.
• Why?
Meniscus• Curve at the top of a liquid in any container
• ALWAYS read from the BOTTOM of the meniscus

Volume of Solids
Two types of objects
Regular Objects
Cube shaped, flat faces, precise edges
Irregular objects
Random shapes, not flat sides, not clear
edges
Regular objects
To determine the volume we use:
Volume= length x width x height
L=
W=
H=
Irregular ObjectsTo measure volume we use Water
Displacement.
0.8 ml 10.0 ml
Steps of Water Displacement
1- Measure the amount of water in the gc before placing the object in.
2- Place the irregular object into the water
3-Measure the combined volume by reading the new meniscus.
4-Subtract the original volume from the combined volume to determine the volume of the irregular object
