Set of 3 Cylinders, Equal in Volume U8403315

Instruction sheet

11/07 ALF

1 Aluminium cylinder
2 Iron cylinder
3 Brass cylinder

1. Description

The set of three cylinders, equal in volume, is used
for determining the densities of different solid bod­ies. The set consists of one cylinder each of alumin­ium, iron and brass. As they are of identical volume,
the difference between the densities is immediately
obvious to the student.

Each cylinder is equipped with a hook.

2. Technical data

Materials: Aluminium, iron, brass

Dimensions of cylinders: 40 x 20 mm

3. Sample experiment

Determination of the densities of solid bodies

To determine the density the following equipment is
also required:

1 Electronic scales 600 g U42050-230
or
1 Electronic scales 600 g U42050-115

1 Beaker from U14210

• Place a cylinder on the scale and record the

weight.

• Fill the glass beaker with water.

• Suspend the cylinder from the hook of the scale.

• Immerse the cylinder completely in the water

and again record the weight.

As a result of the upthrust, the apparent weight of
the body is reduced by an amount equal to the
weight of the volume of liquid that it displaces.

• Note the difference in weight, and from that

calculate the volume of the cylinder.

• Calculate the density of the cylinder using the

equation

• Repeat the measurements with the other cylin-

ders and compare the results.
