How did Archimedes solve the gold crown problem?
hi
What problem did king hiero want Archimedes to solve?
During Archimedes' time in Syracuse, King Hieron, the king of Syracuse and a close friend of Archimedes, commissioned the construction of a beautiful golden crown. When the goldsmith returned the crown, the king suspected him of stealing some of the gold and replacing it in the crown with silver. The king wanted to make sure that he got all of his gold back, so he asked Archimedes to discover the true contents of the crown.
How did Archimedes solve the King's problem?
He discovered the difference in density between gold and silver when placed under water, and noticed that the crown was not pure gold. The crowns maker was later beheaded.
1kg gold and 1kg cotton which is heavier?
Nooo, 1kg gold is heavier 1kg cotton, because the last one has much more volume than the first, so Archimedes force reduces weight of a cotton more!
Is gold a concrete noun?
Yes, the noun 'gold' is a concrete noun, a word for a physical substance.
What was the events leading to Archimedes discovery of gold?
The event leading to Archimedes discovery is finding gold
What did Archimedes have to do with gold?
Alot
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 did Archimedes want?
Archimedes wanted to know the density of gold to determine if the crown was partially silver rather than all gold.
Why did Albert Einstein say eureka?
He was quoting the exclamation attributed to Archimedes, who is said to have cried out "Eureka! eureka!" (I have found it! I have found it!), Eureka is Greek for "I have found it". Archimedes said it when he discovered how to use water displacement to test the purity of gold.

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 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.
Who invented the law of displacement?
The mathematician Archimedes of Syracuse.The most common story (which was first told by Vitruvius but doesn't pop up in Archimedes' known works) goes that King Hiero II had a votive crown forged for a temple, and he supplied the pure gold the goldsmith was to use. However, when he got the crown, the King asked Archimedes to determine whether the goldsmith had used all of the gold supplied or substituted silver for some of the gold. Archimedes couldn't melt the crown down into a regular shape to find its density, because he had to leave the crown intact, so he puzzled over the problem for some time. While taking a bath one day, he noticed that the water level rose as he stepped in, and realized that he could use this effect to solve the problem, and supposedly ran through the streets screeching "εὕρηκα!" (heureka!, Greek for "I've found it!") naked. When he performed the test with the crown, he found that the goldsmith had indeed substituted silver for some of the gold.
What role did gold play in an archimedes' great discovery?

How do you measure the density of an irregular object that doesnt float?
Ah, the Eureka question. The original questioner in recorded history was of a Greek king whose crown was supposedly made of pure gold. At least the king had given the jeweler a given weight of pure gold and the new crown weighed exactly that amount when it came back. But, the king became suspicious and wanted to be sure his crown was pure gold and the jeweler had not substituted a baser metal for part of the gold. The king sent for Archimedes who had solved many of the kings problems and asked Archimedes to devise a test for making sure the crown was pure gold. Archimedes thought long and hard over the problem. As the legend goes (and it almost certainly didn't happen this way as Archimedes never wrote about it and the first recording of the legend was about 200 years after Archimedes died), when Archimedes lowered himself into the public baths in Syracuse, the displacement of water from his body caused the bath to overflow, thus giving him the insight in how to measure the volume of an irregular shaped object. Archimedes, according to the legend, then went running naked through the streets of Syracuse yelling "Eureka" which translated means "I have found it." So, to get to your answer, the density of an object is by definition the mass divided by the volume. First obtain the mass of the object, usually by weighing it. Now determine the volume by immersing your object into a full container of water and either measuring the amount of water that overflows out of the container, or preferably (at least to my mind) measuring how much water it takes to refill the container. Divide the mass by the volume and you have the density.
