how could you measure the vol of an object by the water displacement method?(Read The Details I Added!)?

Question

base your answer on the fact that the object did not fit in the graduated cylinder. assume you only have a seperate beaker or jar large enough to entirely contain the object.

Answer 1

These were known as "Eureka cans".

You fill the large container with water and let the excess drain out of the lip of the beaker.

Once the excess water has finished draining off, place the graduated cylinder under the lip of the beaker to collect the water.

Lower the object into the breaker and the water it displaces will be collected in the graduated cylinder.

Once the water has finished draining again, you can now easily read the amount of water in the cylinder and know the volume of the object.

I hope this helps?!

Answer 2

All the answers that you got so far want you to collect the overflow water into the measuring jar (graduated cylinder). Well, I have a different idea with the same set up.

First fill the other jar or beaker to the brim with water. Then slowly dip the object till it is completely immersed. Let the overflow, go off. Now, take out the object and fill the jar with water from the graduated cylinder till it is again filled to the brim. The volume of water added will be equal to the volume of the object.

Answer 3

The guy who shouted 'Eureka' (I've found it) was indeed Archimedes.

He said " When a body is partially or totally immersed in a liquid, the apparent loss in weight is equal to the weight of liquid displaced". The volume of liquid displaced is therefore equal to the volume of the body.

Assuming you don't have a 'Eureka' can: -

Fill your jar with water until it is brim full and overflows. Wait until the overflow stops running and carefully place the jar in a larger, completely empty container. Place your object in the jar.

This will displace a quantity of water into the container.
Carefully lift out the jar and object, without spilling any into the container. Again, carefully drain the container into a measuring cylinder and wait until all drips have finished.

The volume of water in the cylinder will be equal to the volume of the object (ignoring the small amount wetting the inside of the container).

Answer 4

You put the beaker in a pan or something similar, fill it completely to the top with water. Place the object in the beaker and pour the overflow into a graduated cylinder.

That will give you the measurement of it's displacement.

Answer 5

Fill the jar right to the brim with water.
Slowly immerse your object - whilst collecting the overflowing water.
You can now tip this into a measuring cylinder and hey presto !! You have the volume.....

This is known as Archimedes Principle (Remeber he was the guy in the bath who shouted EUREKA !!)
