The goal of this exercise is for your group to identify the composition of a small metal object. You will make a series of measurements and calculate its density, together with an uncertainty. Then you will use that density to pick several possible materials from a table of metals.
Here are the devices you will have:
You should follow these steps:
The following values can be found at The Engineering Toolbox .
Metal Density (kg per cubic meter) ---------------------------------- Aluminum 2712 Beryllium 1840 Brass 8400 - 8700 Cobolt 8746 Copper 8930 Gold 19320 Iron 7850 Lead 11340 Magnesium 1738 Mercury 13593 Nickel 8800 Platinum 21400 Plutonium 19816 Silver 10490 Steel 7850 Titanium 4500 Uranium 18900 Vanadium 5494
