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.
It is not. They have exactly the same mass and so must have the same weight.
Using terms like "less dense" or "more dense" provides a clearer and more specific indication of the object's density compared to simply using "lighter" or "heavier." Density refers to the mass of an object relative to its volume, so it's more accurate to refer to it as less or more dense rather than just lighter or heavier.
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.
No, both a kilogram of feathers and a kilogram of lead would weigh the same, as they both have a mass of one kilogram. However, the volume of feathers would be much larger than the volume of lead due to their different densities.
No, 20kg of lead and 20kg of feathers would have the same mass in vacuum since both are 20kg. Gravity does not affect mass.
Of course not.A small jar of lead will be much heavier than a slightly larger jar of feathers.
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!
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.
