Equal Mass Metal Cylinders Set
Product Code : EL-MM-11006
Quick answer: The Equal Mass Metal Cylinders Set shows density at a glance: six cylinders of brass, lead, copper, iron, zinc and aluminium each have a mass of 100 g and a diameter of 16 mm, so the denser the metal, the shorter the cylinder. The set stands in a wooden holding block. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the density demonstration is done
Density is mass divided by volume (rho = m / V). Here the mass is fixed at 100 g and the diameter at 16 mm, so the volume of each cylinder, and therefore its length, depends only on the density of the metal. Standing the cylinders side by side in the block turns the idea into a picture: aluminium, the least dense metal in the set, gives the longest cylinder and lead, the densest, the shortest.
- Weigh two or three cylinders to confirm that each has a mass of 100 g.
- Measure the length of every cylinder and check the 16 mm diameter.
- Work out each volume from V = pi x r^2 x length, with r = 0.8 cm.
- Calculate the density of each metal as 100 g divided by its volume in cm3.
- Compare the results with textbook densities and discuss the causes of any difference.
A quick visual version needs no measuring: students rank the cylinders by length and predict the density order before checking it by calculation. Volumes can also be confirmed by displacement of water in a measuring cylinder. Students should wash their hands after handling the lead cylinder.

Frequently asked questions
Why are the cylinders in the equal mass set different lengths?
All six have the same mass (100 g) and the same diameter (16 mm), so a denser metal needs less volume and gives a shorter cylinder. Aluminium is the longest and lead the shortest.
Which metals are included?
Brass, lead, copper, iron, zinc and aluminium, one cylinder of each.
