Hey mate ^_^
1) It is a can which is filled as high as possible with water and an object inserted slowly into it. As the object fits into the can, the water it displaces pours out of the spout. This displaced water can then be measured and will be the same as the volume of the object.
3) It is a small bottle or flask used to measure the specific gravities of liquids and this bottle is weighed when it is filled with the liquid whose specific gravity is to be determined, when filled with a reference liquid, and when empty.
5) Because of Buoyancy, any object will either float or sink in water depending on its density. If it's more dense than water, it will usually sink; if it's less dense, it will float.
And waterline refer to any line on a ship's hull that is parallel to the water's surface when the ship is afloat in a normal position.

This is a piece of science equipment that uses liquid displacement to measure the the volume of a dense or solid object.
For example: If I want one half cup of shortening I will fill a measuring cup with one half cup of water then spoon shortening in to cup until water reaches the one cup mark.
One half cup of water is displace giving me one half cup of shortening.
Density is calculated from Density = mass/volume.
To find the mass you simply weigh the object (grams).
To find the volume you place the eureka can ion a horizontal surface and fill it with water. You wait till the spout finishes dripping (catch the water and discard it). You then place an appropriately-sized measuring cylinder (graduated cylinder) beneath the spout. And gently lower your object into the can. (It jelps to lower it, ties to a length of thread to minimise splashing.
You then record the volume of water displaced cm^3) and use it to compute your answer.

Specific-Gravity Bottle
: a pycnometer having the form of a stoppered bottle
A ‘density bottle’ has a mark on it indicating a specific volume - let’s say for illustrative purposes, the mark corresponds to 1 mL.
Ok, now, with nothing in the bottle (except air), weigh the bottle. Let’s say - again, for illustrative purposes, the empty bottle weighs 5 grams.
Now, fill to the mark with the liquid. Weigh again. Let’s say it now weighs (bottle+liquid) 6.5 g. So, the liquid weighs 6.5–5 g = 1.5 g. The volume is 1 mL and the density is 1.5 g/1 mL.

The reason that a ship floats is that it displaces a lot of water. The displaced water wants to return to it's original location, where the ship is now, and this pushes the shipupwards. The force which pushes the ship up is called the buoyancy force.
