Sand is denser than feathers. Since a given volume of a denser material has more
mass than the same volume of a less dense material, when you make the masses
the same, the volumes must vary.
Kilograms are a measure of mass, not weight (weight is a type of force, which is measured in newtons or pounds-force). It depends entirely on where you measure them, but if measured in the exact same place, they would weigh exactly the same too.
Other answers have been moved to the discussion area - where they should be since they only discuss - as they do not answer the question in any meaningful way.
Because bricks have higher density than feathers have.
That they weigh the same!
The difference is that the density of lead is far greater so it takes up a lot less space to make up a kilogram.
They both have the same mass. Same weight, too.
An objects Inertia is directly proportional to it's mass. Same mass same inertia, so same.
A kilogram is a kilogram. They weigh the same.
The kilogram of feathers and the kilogram of metal have the same mass and the same weight. However, the kilogram of feathers has a much larger volume than the kilogram of metal.
2 kg feathers
They have the same mass.
a pound of bricks. Air can flow through the feathers so that causes it to float down. feathers don,t fall. they glide. but everything falls at the same speed. i cant remember what you call the air flowing though the feather but i know it cause im in sixth grade. If you drop both of them in space, then they will fall at the same time. Even though their mass is different, there is no air resistance in space. Air resistance is the force that is like acting against gravity. In Earth, there is air resistance, so in the case of the feather, there is more air resistance acting upon it than the gravity. That is why it falls slower than the pound of bricks.
Mass takes up space. Say, 50 square cu. ft. of feathers has more mass than 25 square cu. ft. of bricks. Weight is the gravitational pull on an object. Because bricks weigh more than feathers, bricks would have a srong gravitational pull. Mass takes up space, and weight is how strong an object's gravitational pull is.
it might explode if you put it in a smaller space.
1 cubic decimeter of pure water is 1 liter and weigh 1 kilogram. A mass of one kilogram is a weight of one kilogram at sea level. If you move your subject into space, it will weigh less. If you take it to Jupiter, it will weight more, but its mass will remain one kilogram.
lead is much more dense than feathers, so 1 kg of lead occupies much less space (volume) than 1 kg of feathers
It takes alot more feathers to equal a kilogram than it does bricks
the densities are different
the densities are different
Bricks have a higher density- the molecules are packed much more tightly.
the densities are different
because sand is smaller than feathers and it would take up as much space with the sand , and if the feathers were there it would take up more space because its and larger object than the sand .
Neither. They both have the same mass. "kg" is a measurement of mass. If you meant volume (the space taken up by the object), the feathers would have the greater volume.
Bricks have more density whereas feathers have less comparatively. Space occupied ie volume = mass/ density. So space occupied is inversely related to the density. Hence feathers occupy more space than the bricks.
A pound of bricks and a pound of feathers weigh the same because they both weigh one pound. The difference lies in their volume, with bricks being denser and taking up less space compared to feathers.
A kilogram of sand takes up much less space than a kilogram of feathers because sand is denser than feathers. Density refers to how much mass is contained in a given volume. Since sand particles are heavier and more compact than feathers, they occupy less space for the same mass.
The answer is very much the same as the answer to the question: "Which weighs most, hot water, cold water, or water colored green ?" The answer, of course, is: That depends on how much you have of each substance. One thing we can definitely guarantee: A pound of bricks, a pound of cheese, and a pound of feathers all have precisely the same, identical, and indistinguishable weight.
A ton of brings does not exist, but if you mean a ton of bricks or a ton of feathers, they both weigh the same - 2000lbs. A ton is an imperial unit of measuring weight - it doesn't measure volume (or space that on object takes up). A ton of bricks would be relatively compact, while a ton of feathers would take up an enormous amount of space.
