You can either:
1. Hit it with a hammer. If it flattens, it is gold.
2.Rub it on a tile. If the mark is gold colored, it is gold.
Hope this helps!
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.

To determine if a sample of gold is pure, you can conduct various tests such as acid testing, density measurements, and conductivity tests. These tests can help identify any impurities in the gold sample and assess its purity level. It is also common to have the gold sample evaluated by a professional assayer or jeweler for an accurate purity assessment.
The sample could be described as pure gold or 100% pure gold.
To check if your gold is pure, you need to compare its weight to the weight of a known sample of pure gold. If the two weights are equal, then you can be confident that your gold is pure.
One common method to determine if gold is pure is through acid testing. A sample of the gold is tested with nitric acid, and its reaction or lack thereof can indicate the purity. Alternatively, professional jewelers may use tools like a spectrometer or X-ray fluorescence to analyze the composition of the gold accurately.
step 1. well you can put it in water and measure the variance step 2. you should theoretically calculate the amount of water that will be raised and you can know whether it is pure or not
The determination is by chemical analysis.
One way is if it can be physically combined.
Gold is very dense, so a pound of it won't displace much water. If a crown, supposedly of pure gold and weighing one pound, displaces MORE water than a pound of bar gold does, then the crown is LESS dense than gold and is therefore amalgamated with some less dense material. Archimedes' problem was really how to measure the VOLUME of such an irregular shape as a crown.
You may be referring to the story of how Archimedes was able to determine if a crown had been made of pure gold (or less-than-pure gold) by measuring how much water the crown and an equal weight of pure gold displaced.
Gold is an element; a molecule of gold (Au) is the smallest amount of gold that you can have that is not dividable into smaller amounts of gold. Whether or not a sample of gold is pure depends on the presence or absence of alloys or impurities blended with the gold.
