Table 2:
Volume Displacement
The table above displays the different displacements between each metal.
Analysis:
From the experiment, the conclusion was agreed to be that metal one was steel, metal
two was aluminium, metal three was lead, metal four was brass, metal five was lead, and metal
six was aluminium.
Calculations:
sphere V=4/3π^3
rectangular prism V= L x W x H
right circular cylinder V= πr^2 H
pyramid V= (L x W x H) / 3
prolate ellipsoid V= 4/3 πr^2 (L/2)
right circular cone V= πr^2 (H/3)
Density = Mass/Volume
volume of water - volume of water and metal = volume of metal
Discussion and Conclusions:
From what can be seen, one can assume that the displacement of water is a better method to find
density. This is due to being able to find the density of irregularly shaped objects easier than
taking the dimensions of every part of said object. Metals 1, 2, 4, 5 and 6 are alloys. An alloy is a
substance that combines multiple metals/a metal with non-metals.
