For an object to flat it must displace more water than it weighs. So a 1 kg hollow steel ball bust displace 1kg of water. 1 kg of water has a volume of 1 litre so the steel ball must have a volume greater than 1l. Note: 1lite = 1000cm^3

For the steel ball to float in water, its density must be less than that of water, which is 1000 kg/m³. Given that the ball weighs 1 kg, its volume must be greater than 1 liter (1000 cm³) for it to displace enough water to float.

Why do hollow things float?

Hollow things float because they displace a volume of water greater than their own weight. This creates an upward buoyant force that keeps them afloat. The empty space inside the hollow object decreases its overall density, allowing it to float on the water's surface.


A balloon fish that swallows air will float because it weighs less than what?

The balloon fish will float because it weighs less than the volume of water it displaces. By swallowing air, the fish increases its volume without significantly increasing its weight, allowing it to float at the water's surface.


What is the density of an object to do with if it can float or not?

The density of an object determines whether it will float or sink in a fluid. If the object has a lower density than the fluid, it will float; if it has a higher density, it will sink. This is because objects with lower density displace an amount of fluid that weighs more than the object itself, causing it to float.


What describes how much something weighs compared to its size?

Density describes how much something weighs compared to its size. It is calculated by dividing the mass of an object by its volume, and it helps determine whether an object will sink or float in a fluid. Objects with higher density will sink in a fluid, while those with lower density will float.


How much upthrust does something need to float?

An object needs an upthrust that is equal to or greater than its weight in order to float. This is known as Archimedes' Principle. The amount of upthrust required for an object to float depends on its density and volume.

Can a ball float in water?

Depends on how much it weighs, if its hollow then maybe it would float. But doubting it would if its solid.

Will kilogram float in water why?

The mass of an object alone is not enough to determine whether it will float in water. You need to know the object's mass and its volume; in other words, its density. A kilogram of solid lead will sink in water. A kilogram of styrofoam will float. If an object is less dense than water it will float; if it is denser it will sink.

Why can metal float?

For something to float, it must displace the same amount of water as it weighs. Answer:To float in water, a solid metal object must be lighter than the water equivalent to its volume. This would make lithium (at S.G. 0.53) the only metal that would float in water.Objects which are hollow and made of metal float because the contained volume of the object divided by the weight of the object is less than 1 gm/cm3, the density of water. Solid metal objects can float in liquids which have a density greater than they exhbit thesmelves. As an example, almost all metals will float in mercury

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.


Does a piece of copper floats in salt water?

Without seeing the piece of copper you have, it's hard to say.An object will displace a volume of water equal to its weight. This is how a ship that weighs over 100,000 tons can float: the volume of the ship is greater than the volume of 100,000 tons of water. The ship pushes aside (or "displaces") 100,000 tons of water, and the rest of the ship rides above the surface.Now for your piece of copper: If it's solid, the copper will weigh more than an equal volume of water. If it can't push aside water equal to its weight, it'll sink. If the copper is hollow, it will weigh less than an equal volume of water, and will float.


What is the density of an object to do with if it can float or not?

The density of an object determines whether it will float or sink in a fluid. If the object has a lower density than the fluid, it will float; if it has a higher density, it will sink. This is because objects with lower density displace an amount of fluid that weighs more than the object itself, causing it to float.


How do you make a ship out of metal float?

What detimines whether an oject will sink or float is the amount of fluid that it displaces. If the amount of fluid displaced weighs more than the object then it will float, if it weghs less it will sink. A boat can be made of any material, even concrete.
