Was Archimedes crown pure gold?

Yes Archimedes crown was pure gold. how they know this is that they weighed the dentisity of the crown.


What is Archimedes gold demur?

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.


How did Archimedes prove the king's crown was pure gold?

Archimedes thought that if the gold crown and the gold bar had the same mass and volume, the crown was pure gold and if they didn't, the crown was a fake and the jeweller was a fraud. (I just had to do this for homework. I'm right!)


How does the acrchimedes crown story relate to matter?

The Archimedes story relates that Archimedes had been trying to determine if the King's crown was pure gold, without having to melt it down (destroying it) to see. Archimedes sat down in the tub and noted that the water rose in the tub, and that he realized that the volume of water displaced was equal to the volume of Archimedes himself. This gave him an insight into how to determine the volume of the crown; by submerging the crown in water and measuring how far the water rose, this would give him the volume of the crown. He could then weigh the crown and calculate the density of the crown, and determine that the crown was not pure gold.


How did Archimedes find out the crown wasnt gold?

By studying the displacement of water caused by pure gold and silver of the same mass, he proved that the gold crown was not of pure gold as claimed by the jeweller.


How was density used to detect fraud?

Archimedes was told by the king to find out if his crown was made of pure gold, calculating the density of the crown, Archimedes found it to be a mix of gold and silver.


If Archimedes had only been able to find a piece of pure gold with a mass one - half that of the crown how could he have determined whether the crown was pure gold?

Archimedes came across concept of density - that is MASS divided by VOLUME. For each substance this ratio is different but a CONSTANT for that substance. Thus the mass you are dealing with is irrelevant if the crown had the same ratio as the piece of pure gold then the crown was pure god, if it did not then the crown was not gold.

How did Archimedes find out that the kings crown is not pure gold?

he could Tell by the colour and the weight


How do you determine whether or not the crown was pure gold or not?

you weigh its density and compare it with the density of gold, if both densities are same, then the crown is made of pure gold. if the density of the crown is lower than the density of gold, then the crown is made of materials that are cheaper or have a density that is less than gold, meaning that it is not made of pure gold.


Why couldn't Archimedes work out the volume of the crown by measuring it with a ruler?

different objects have a different density so since gold is more dense than silver the crown made of pure gold would be heavier than the silver crown.
