They both weight a kilogram. Lead has a higher density.
They both weigh one kg, so they should have the same weight.
Please note that a kilogram is a unit of mass - NOT a unit of weight. And yes, a pencil has a mass that is considerably less than a kilogram. For comparison, a kilogram is the mass of a liter of water.
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 has much higher density
They both weight a kilogram. Lead has a higher density.
They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
Butter has greater volume than lead because butter has more mass.
This statement is incorrect. A kilogram of lead always weighs the same as a kilogram of air since they both have a mass of one kilogram. However, lead is denser than air, so a kilogram of lead will occupy less space compared to a kilogram of air.
They weigh the same, as both are 1 kilogram. The weight is determined by the mass of the objects, and in this case, they are both 1 kilogram.
Both would weigh 1 Kilogram with a difference of volume.
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 ?
A kilogram of water and a kilogram of lead have the same mass, but lead is denser than water. Lead has a higher density because it has more mass packed into a smaller volume compared to water.
erm, 49 kg?
Volume is the amount of 3-dimensional space occupied by an object and has nothing whatsoever to do with the molecular composition of the object. The volume of a 1" x 1" x 1" cube of lead is exactly the same as the volume of a 1" x 1" x 1" cube of butter or a 1" x 1" x 1" cube of anything for that matter. Lead and butter have a great many differences, but volume isn't a measure of any of them.
Both a ton of butter and a ton of lead would weigh the same, since they are both one ton in weight.
The attraction of the Earth for a kilogram of lead is equal in magnitude but opposite in direction to the attraction of kilogram of lead for the Earth, according to Newton's third law of motion. Both objects experience an equal gravitational force due to their masses.
