it is obviously the same weight because it say KILO for both!
One litre of feathers would have far less mass than one litre of lead.
They are both exactly the same - they weigh a pound. However, the feathers will take up a lot more space (about 0.77942 litres for every kg of feathers - or 779 cm3/kg) whereas the lead would be much smaller (about 0.12700 itres for every kg of iron - or 127 cm3/kg).
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.
Pounds are a unit of weight and centimeters are a unit of length. We can't convert one to the other. Something that weighs 160 lbs will have dimensions, but the dimensions of 160 pounds of lead will be vastly different from the dimensions of 160 pounds of feathers.
a square foot of lead has no weight since it has no thickness
They are the same weight
Neither. The weigh the same.
They all would weigh the same amount, 1 Kilogram.
Because lighter and heavier refer to an objects weight - which has nothing to do with density ! For example - a kilo of feathers is heavier than half a kilo of lead - but lead is more dense !
It is not. They have exactly the same mass and so must have the same weight.
No, both weigh a kilogram
Lead is unquestionably heavier than an equal volume of feathers.
Because 1 kg of lead can be easily carried in one hand as opposed to the sise of the container you would need to make up 1 kilo of feathers, as a matter of fact it would be impossible to Carie 1 kilo of feathers without a container of some sort.
A fluid ounce of water weighs slightly more than a dry ounce (1 fluid ounce of water weighs 1.043 dry ounces). Therefore a fluid ounce of water is heavier than a dry ounce of flour (or anything else for that matter). Note that a fluid ounce of something else might NOT be heavier. A fluid ounce of lead is much heavier than a fluid ounce of feathers!
Lead is heavier than iron.
Of course not.A small jar of lead will be much heavier than a slightly larger jar of feathers.
By definition, they have exactly the same mass.
