Best Answer

He took the weight of the crown and then used water displacement to determine the volume. He could then deduce the density of the crown. Various types of metals have different densities. Density is the mass to volume ratio. Or in better terms, how tightly the molecules are packed together in a substance. If the density of the crown was different than that of any other piece of gold, it was not gold. The bath make him weight then die.

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.


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 Archimedes find or discover Archimedes principal?

According to Vitruvius, a new crown in the shape of a laurel wreath had been made for King Hiero II, and Archimedes was asked to determine whether it was of solid gold, or whether silver had been added by a dishonest goldsmith. Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body in order to calculate its density. While taking a bath, he noticed that the level of the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible, so the submerged crown would displace an amount of water equal to its own volume. By dividing the weight of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added. Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying "Eureka!" (meaning "I have found it!")


When do you stumble across the answer to a problem?

Solutions to problems can 'hit' you at any time. Take Archimedes for example. He was asked to determine whether a crown that had been made for King Hiero II, was as pure as the gold that had been supplied to make it, or if some silver had been substitued. The only problem Archimedes had - was that he was not allowed to damaging the crown. While taking a bath, he niticed the water level changed as got in and out - and realized that this level change could be used to find the volume of the crown. The submerged crown will displace the same amount of water as its own volume. Dividing the mass of the crown by the volume of displaced water, gives the density of the crown. The density would be lower if cheaper metal were added. Archimedes was so xcited by his discovery, he apprently leapt from his bath, and ran naked through the streets to the palace, crying 'Eureka !' (Greek for 'I have found it'). The same test was conducted on the crown - successfully proving that silver had been mixed in with the gold.

What is the story behind Archimedes principle?

The Story Behind the ScienceHieron, the king of Syracuse and Archimedes' friend, wanted to know whether his crown was made of solid gold. The king suspected that the gold had been mixed with silver, which is worth less than gold. So he asked Archimedes to try to resolve the question. The solution would have been easy if the king had allowed the crown to be melted down. Since that was no possible, Archimedes had to find another solution to determine the metal content of the crown. Archimedes discovered the answer while at a public bath. He noticed that when he got into the water, it overflowed the tub. By measuring the overflow, he found that the volume-the amount of space a thing occupies-of the spilled water was equal to the volume of his body under water. He realized he could determine the gold content of the crown by measuring the water it would displace against the amount of water displaced by a lump of gold weighing the same as the crown. The crown and lump of gold would each displace the same amount of water if the crown were solid gold. If the crown contained silver, it would displace more water, since the volume of a weight of silver is greater than the volume of the same weight of gold. With this discovery, Archimedes leaped from his bath and in his excitement raced naked down the street toward his home, shouting "EUREKA! I have found it!"Archimedes was the first to develop the physical law that is now known as Archimedes' law. The law explains buoyancy, or why objects seem to lose weight in water or other liquids. This principle has been applied ever since to test precious metals.

How was buoyancy invented?

Buoyancy wasn't invented by anyone, but it was first discovered by Archimedes. He never considered about buoyancy until one day, he had to help the King solve a problem, which got him stirred about buoyancy.Bouyancy has always been around. Archimedes simply understood it when he saw the bath water rise as he got in the bath.As the story goes, the king wanted to know if the goldsmith alloyed some silver in with his crown, and asked Archimedes to find out. Archimedes thought about this and one day discerned the principle at the bath. It is claimed that he jumped out and ran back to him home naked shouting Eureka!He took a lump of gold with the same mass as the crown, and a lump of silver the same mass as the crown. He then measured the displacement of water by the gold, by the crown, and by the silver. He discovered that the crown displaced more than the gold, but less than the silver. He concluded that the crown was not pure gold, and must therefore have been alloyed with silver. The king promptly executed the goldsmith.

Who Archimedes was?

Archimedes and his inventions, Properties', and Math Archimedes was an impressive scientist and mathematician as well as a potent inventor. He was the creator of Pi, defender of Syracuse, and a genius on top of that. We shall see with our minds eye how he applied himself in various situations. The golden crown was one of the first causes of Archimedes discoveries. King Heiro II asked to find out if a goldsmith had cheated him in making his new crown. King Heiro thought the goldsmith had mixed in cheaper silver. Since Archimedes could not melt the crown down and compare it to an equal amount of gold he had to come up with a different idea. The answer came to Archimedes in a bath. When Archimedes got in the bath it overflowed. This gave Archimedes an idea. Forgetting to dress he ran outside screaming "Eureka." "Eureka." This in English means I found it. By putting an equivalent of the gold that's in the crown in water and marking it they could find out if they used lighter silver in the crown. When the crown was submerged the water did not reach the line proving the goldsmith had cheated the king. Archimedes made several inventions. The Archimedes's Screw was a device that could be used as a pump as seen in the visual aid (display working of screw) another invention of his was the planetarium the small planets were moved by a series of gears inside the machine. However, the device was never found. Also he claimed to have invented a death ray that focused the sun's rays onto one spot and could be used to light ships on fire. This was proven wrong in 2007 by the show Mybusters. Archimedes spent a great amount of time working with math and geometry. He is credited with inventing Pi which is used to find the perimeter and area of a circle. People said that he spent most of his time drawing shapes and quoting one of his servants. "When he did let us bath him he would draw on his own body during the bath." Archimedes final months were spent defending Syracuse from Roman soldiers. The Roman Empire sieged Syracuse from the land and from the sea. The naval attack was first. The attack was foiled by siege engines and Archimedes personal weapon the claw of Archimedes. The claw acted like a crane a rope on the end was attached to enemy ships once secure the claw was swung up flipping or capsizing the ship. A few days later a group of marines attacked in the middle of the night. And instead of walking up the path to the city people behind walls shot iron spikes at them from catapults forcing them to retreat. The land assault was likewise. The Romans blockaded the trade routes and made Syracuse starve for six months with they attacked again. This time they entered the city. A roman solider slew Archimedes in the attack. His last words were "Do not disturb my circles." The moral focus trait that radiates from him appears to be wisdom and he used it when making most of his inventions and laws. He used it in making the Archimedes Screw, Pi, and in figuring out the golden crown. The water screw is still used today as well as Pi.


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.

Why is Archimedes called the greek streaker?

The King at the time gave a man gold to mold a crown. When the crown was finished it felt lighter than the gold given so the king accused him of stealing gold. Archimedes was sent to measure the density of the crown but he wasn't aloud to melt it so he had to find a new way. He took a bath and noticed that the water rose when he went inside, so he ran butt naked to the king to say "eureka" and that's how we got measurement by water displacement and that's how he got the title "The Streaker"


Why did Archimedes shout 'eureka'?

According to legend, Archimedes shouted "Eureka!" (which means "I have found it!") while running down the streets naked. The reason he did this is because he found out that, a body immersed in water has a buoyant force equal to the weight of the water that it displaces. He was able to find out if the kings crown was really made of pure gold this way (and it wasn't).
