What is the density of a boat?

What is the density of your average boat?

That question has no answer, because I don't own a boat. But regarding any boat in general, if the boat is afloat, then its density is less than 1.0 .

Why do boats with water sink?

When the density of entire assembly (boat, peoples, products, equipments, water etc.) has a density greater then the water density the boat is sinking.

What part of the boat makes it float?

The boat floats because the entire boat - including any air contained within - has a total density less than the density of the water.

If a boat is sinking because it has to much cargo How does density compare to the density of water?

If a boat with too much cargo is sinking, it means the combined density of the boat and cargo is greater than the density of water. Water has a density of 1 g/cm^3, so anything with a greater density will sink. To stay afloat, an object must have a density less than that of water.

How does a boat not sink?

the boat has equal or less density than the water. :P

How do you change the overall Density of a boat?

I don't understand what you're asking, so I'll reply based on the literal meaning of your question. One way to change the overall density of a boat is to take it apart and make it out of a material with a different density. You could just add ballast or cargo.

How does changing the shape of the metal affect the density of the boat?

Indeed yes. Density is defined as mass per unit volume. If all the mass were concentrated in one lump, your boat would no longer float. If the metal walls of the boat were a little thinner, you'd have more boat volume, and lower density.

What is density of iron boat?

That depends on how much gargo it's carrying. But if it's floating, then its density is less than 1.0 .

Why will a hollow boat made of plasticine float?

A hollow boat made of plasticine will float because the overall density of the boat is lower than the density of water. The buoyant force acting on the boat is greater than its weight, allowing it to float on the water's surface.

If you know the width length and mass of a boat how can you calculate how deep it will sink in water?

Well, darling, to calculate how deep a boat will sink in water, you need to consider its volume and density. The volume can be calculated by multiplying the length, width, and depth of the boat. Then, you can divide the mass of the boat by its volume to find the density. Finally, you can use the density of water to determine how deep the boat will sink. Voila!

What is the density of water vs density of a boat?

The density of pure water is approximately 1000 kg per cubic meter. It isn't, strictly speaking, useful to compare the density of a boat to the density of water. A boat can be constructed of material considerably denser than water (consider a steel battleship or aircraft carrier) and still float. What's important is that the boat must be able to displace a volume of water equivalent to the weight of the boat, without allowing the water to enter the boat. ---------------- Addendum ---------------- The answer your teacher is looking for: "The density of the water is greater than the density of the boat.". This answer is not correct in all cases. If the actual displacement of the boat (sans air) is used to determine density, all steel boats would be denser than water, and most motor boats would be denser than water. A boat which (sans air) is less dense than water cannot fully sink. Now for the next phase of comprehension: the boat has a degree of buoyancy not just in the water, but also in the air. To measure the total bouyancy (which is 0 while floating), you must understand that the mass of the displaced air (above water level) and the mass of the displaced water (below water level) is the sum of the mass of the air (below water level) and the boat (without air). Were the air denser than the boat, the boat would lift (sans surface tension) from the water and float away in the air.

Why does water density affect boats floating?

The water density is higher than the boat's therefore it floats on the water.
