What is volume

1
What is volume?
2
Volume is the amount of space an object occupies
which makes it a 3-dimensional measurement.
3
What is the base unit for volume?
4
liter
5
Why does volume have a derived unit?
6
In order to measure the volume of a regular
solid, you must use a ruler to measure each side
in cm and then multiply all sides together.
After multiplying cm x cm x cm, your final unit
is cm3. Since cm3 actually comes from length,
you are using a length measurement for the volume
of a regular solid. The unit cm3 is derived from
length but is used for the volume of a regular
solid.
7
What is a meniscus?
8
It is the curve at the surface of a liquid in a
graduated cylinder, and you should read the
bottom of it to determine the volume of a liquid.
9
How do you find the volume of an irregular solid?
10
Water displacement
11
What are the steps for water displacement?
12
1 put water into a graduated cylinder and read
the bottom of the meniscus
13
2 place irregular solid in the water and read
the bottom of the meniscus
14
3 subtract the two water levels and that is the
volume of the irregular solid
15
How do you find the volume of a regular solid?
16
Multiple length x width x height
17
What unit should be used when measuring the
volume of a regular solid?
18
cm3
19
How do you find the volume of a liquid?
20
Use a graduated cylinder and read from the bottom
of the curve (meniscus).
21
What unit should be used when measuring the
volume of a liquid?
22
mL
23
How do mL, cm3, and cc compare?
24
They all take up the same amount of space. If
you have water with a volume of 1 mL, a rock with
a volume of 1cc, and a cube with the volume of 1
cm3, the water, rock and cube would all take up
the same amount of space!
25
Is volume the most reliable measurement?
26
No, temperature and the mixing of solutions can
slightly vary volume measurements. For example
In class I was able to easily place the metal
ball through the ring, but when I heated the
metal ball, it was too large to fit through the
ring. The volume of the metal ball increased
just enough to be too big to fit through the ring.
27
You must be able to measure the volume of various
objects and know which unit to use!
28
You need to have a good understanding of the
volume of a mL, cc, cm3, L, and kL. You need to
know when you would use each unit.
