SCALER VS LIQUID NOTES HOW TO

The crown, once fully submerged, would displace an amount of water equal to its own volume, so he could calculate its density by dividing its mass by the volume of the water displaced and compare that density to pure gold.

Of course, the easiest course of action would be to melt the crown down to a less irregular shape and compare its mass to its volume, but Archimedes couldn't do that with something as valuable as a crown! He considered the problem at length and, while in the bath one night, Archimedes noticed the change in the water level in the tub as he got in, and he had an idea. What a fun question! The Greek mathematician Archimedes is said to have faced a similar problem when he was asked by King Hiero II to determine whether or not the king's new crown had been made with pure gold, as requested.

(published on ) Follow-Up #3: How to find the density of an irregular object? Mike's explanation is an example of what is now called 'Archimedes Principle'. He got the idea of how to measure density and, again according to legend, was so elated with his discovery he ran naked down the street shouting 'Eureka, I have found it'. While taking a bath Archimedes noticed the water level rising when he got into the tub. when the Greek king asked him to verify that his gold crown was really gold and not some gold plated fake. That volume is the same as the object's volume.ДЄccording to legend, Archimedes figured all this out in the third century B.C.

You can pour water in from a measuring cup (say one marked in liters) to see how much is needed to fill from the lower mark to the upper mark. Mark the level of the water when the object is completely under. As the object goes into the water, it will force the water up in the container. Take some water, enough to submerge your object. As Tom wrote earlier, there's a way to do this. So the trick is to find the volume V of the irregularly shaped object. That means mass (M) divided by volume (V).

The density just means how much mass per volume.
