Lead
the same
They both weight a kilogram. Lead has a higher density.
The mass of feathers is far greater than the lead. amount = mass So you will have a huge pile of feathers compared to a small chunk of lead to equal a pound
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.
Lead
That depends on the material or the density. Lead shot, or feathers?
No, lead is a dense material and will sink in water. The density of lead is greater than the density of water, so it will not float.
Lead is denser than feathers. Lead is a heavy metal with a high density, while feathers are lightweight and have a low density due to the air trapped within them.

Lead has a greater density than silver. Lead has a density of 11.34 g/cm3, while silver has a density of 10.49 g/cm3.
They both weight a kilogram. Lead has a higher density.
Something that weighs a ton is equal to other things that weigh a ton, therefore a ton of anything is equal to a ton of anything else. Even if it's feathers versus lead or cotton versus cement.
The lead is more dense. Just so you know the volumes listed before each material are irrelevant - each one theoretically has a constant density no matter how much of it there is.

They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
