How does the shape of the boat effect it to sink or float?
The science is called "displacement". If the shape of the boat allows the amount of the boat in the water to be less weight than the water it displaces it will float. If the amount of the boat in the water weighs more than the water it displaces it will sink.
How doboats float without sinking?
Because the mass of the boat is less than the mass of water the boat displaces.
How do you make metal float but not on water?
I can make a iron nail float. Simply melt some lead and the iron will float on top of the lead. Your question seems to be with regard to how do Boats float and the answer is Bouyancy. The Boat displaces a volume of water and if the weight of the displaced water is less than the weight of the boat, the boat will float.
What makes a bost float?
I assume you meant "BOAT"A boat floats because it displaces water... put a boat in the water and it sinks into the surface of the water...the part of the boat beneath water level pushes water out of the way.When the weight of the water pushed out of the way is the same as the weight of the boat, the boat can sink no further.Tho made of steel or other heavy materials, naval architects calculate displacement ( the weight of water the ship's hull pushes out of the way ) as long as the ship weighs Less than the water it displaces, it will safely float.The difference between the weight of the boat and the weight of water it displaces will determine how much Cargo a boat can carry.
When does a object float or sink in water?
A steel needle will float in water as a consequence of surface tension. A boat floats in water because it displaces sufficient air to make its effective density less than that of water. Usually though, solid, spherical objects, for example, will float if they are made of materials that are less dense that water, which is to say that they have less mass per unit volume than water. In ordinary, imprecise language we say things weigh less than water.
What is the key to making a boat float?
The key to make a boat float is that the boat should weigh less (or have less mass) than the water it displaces.

Does polypropelene float?
The density of polypropylene is almost the same as water. Remember that for an object to float it must have a density lower than that of the fluid in which it is being floated. Polypropylene density is slightly less than water but like any other material it can be made to float by molding it into a shape that displaces water eg a boat is made of steel which is more dense than water but it displaces a large mass of water.

How balloons and blimps are able to fly in oceans of air?
Balloons float because of the same principal as how ships float: bouyancy. A ship displaces a volume of water. If the ship's weight is less than the volume of water that it displaces, then it will float. Same is true for a balloon. It displaces a volume of air. If the Hydrogen or Helium in the balloon weighs less than the volume of air it displaces, then it will rise.
What size boat will float with 250 grams and sink with 301 grams?
Anything that displaces less than 302 ml of water, (in addition to the displacement of the empty boat),before the surface comes trickling over the gunwales.
Do rotten eggs float?
Yes, a rotten egg when placed in water will float as the egg's contents wiegh less than the amount of water it displaces.
How are density and the ability of a boat to float related?
According to Archimedes' Principle (which he described in his treatise On Floating Bodies) a body immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces. In the case of a floating boat, if the average density of the boat and the air within its hull is less than the density of the water, the mass of the water displaced as it settles into the water will be equal to the to the total mass of the boat but it will displace a volume less than the volume of the boat, thus enough of the boat will remain above the water to allow it to float.
Why the sailboat floats on the sea?
The weight of the sail boat is less than the weight of the water it displaces. That is its density is less than that of water.
