Displacement of liquid in a graduated cylinder is a method that will work for irregularly
shaped objects.
Some interesting properties are not measured directly, but can be determined by
combining measurements of other properties.
Density
is a characteristic property of a material
and can be a good way to identify an unknown sample. It is usually calculated from the mass
and volume of a sample.
density = mass / volume
or
d = m / V
Example:
A block of wood measures 2 cm by 1 cm by 5 cm. Its mass is 7.2 g.
What is its density?
The
volume
is 2 cm x 1 cm x 5 cm = 10 cm
