A boat floats because the weight of the water it displaces is equal to the weight of the boat, creating buoyant force. A nail sinks because its density is greater than that of water, causing it to be heavier than the water it displaces.

Why should a boat made of metal float?

The size of the boat is equal to the water displaced by the boat. This means, if the boat is bigger then its weight, the boat will float. If the boat is smaller than its weight, it sinks. This is why metal ships are so big.


How long can a ruled paper boat float?

for about ten minutes, then it gets soggy and sinks.


Does a boat depend on its weight to float?

No it depends on its dynamics and the air in the boat that's why when water goes into the boat it sinks a boat could be 1 kg or 1000 tonnes.


Why dont a steel nail float?

A steel nail is denser than water, so it sinks. The weight of the nail is greater than the buoyant force acting on it, causing it to sink to the bottom.


Can a nail float in water?

The nail sinks in water because the gravitational force attracts it downward toward the earth, there is an upthrust of water on the nail which pushes it upwards but, the downward force acting on the nail is greater that the upward force. Hence, the nail sinks in water. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks. The cork floats while nail sinks this happens because of the difference in their densities. The density of a substance is defined as the mass per unit volume. The density of the cork is less than the density of water. This mean the upthrust of the cork is greater than the weight of the cork. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks.


How does a steel boat float and a flat piece of steel with the same mass sinks?

There is air in the boat so the overall density is less. The weight is spread out.


When is a float no longer a float?

When it sinks.


Why does a concrete canoe float but a concrete block sink?

The block isn't aerodynamic, so it sinks. The boat, no matter what it's constructed with, will be able to float if it's in a shape that will be aerodynamic in water.


Does Fimo float?

No, Fimo does not float in water. It is a type of polymer clay that is dense and sinks in water.


Does cobalt float?

no cobalt does not float on water, it has no way for air to seap through, there fore, it cant float


Does mercury float on water?

No, it sinks.


What property causes a boat clay to float and a clay ball to sink?

The property that causes a boat clay to float is its shape and design, which displaces enough water to create buoyancy. In contrast, a clay ball sinks because it doesn't displace enough water to offset its weight.
