A kilogram is a measure of mass therefore a kilogram of lead and a kilogram of feathers have the same mass: one kilogram. They would, however, have different volumes and densities.
One litre of feathers would have far less mass than one litre of lead.
They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
That depends what substance you have a kilogram of.A kilogram of air fills many many cc.A kilogram of water fills only 1,000 cc (1 liter).A kilogram if ice fills a few more cc than a kilogram of water does.A kilogram of lead, gold, or rock fills only a small number of cc.
A cubic inch of lead is about 0.4 pounds. So 10 pounds would be about 25 cubic inches which would make a ball about 3.6 inches in diameter. That is slightly larger than a softball.
it is obviously the same weight because it say KILO for both!
No, both weigh a kilogram
Because of its' mass density. The lead would be much smaller in size.
They all would weigh the same amount, 1 Kilogram.
Yes
Both the feathers and the lead have a mass of 12 g. The trick in the question is that feathers are less dense and have a larger surface area in proportion to their mass, so they would fall a lot slower and be a lot larger than the same mass of lead.
If you had a perfect scale, that could read to, say, the millionth decimal place, and you used it for each, then the lead would weigh more, because its center would be closer to the center of the earth.
Not easier because of the quantity or mass of feathers are larger than 40 lbs of lead
Both would weigh 1 Kilogram with a difference of volume.
The feathers "take up more room" than the lead. It would be hard to compress the feathers to make them as dense as lead. The feathers have more volume.
The density of a material is defined as its mass per unit volume. A given volume of lead has more mass than a given volume of feathers. In common usage mass often refers to weight, but that is not a very exact usage of it. For this question it may be useful however to think of a given weight of lead per volume and a given weight of feathers.If you have a kg of lead, that is a small piece, a kg of feathers is a large amount.So for a given volume, say a cubic centimeter, the weight of lead is much more than the weight of feathers.
Their masses are the same, so they have the same weigh whenever they're both on the same planet. A kilogram is a kilogram, no matter what form it takes. 1 kilogram is the exact same measure. Its like asking which is longer, a centimeter of chalk or a centimeter of candy. It's also the same as asking: What weighs more, a pound of feathers or a pound of lead ?
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.
