When we say that 1 kg of iron / cotton, we mean that it is the apparent weight. As they are already displacing air and by Archimedes' Principle they both are acted upon by the buoyant force directly proportional to the weight of air they displaced, and cotton displaces more air, therefore its actual weight is more than actual weight of iron.
The mass is irrespective on the material.
So, iron or cotton, cement or gold, 100 kg remain 100 kg.
They are both one kilogram, so they weigh the same.
However, cotton is less dense than iron, so one kilogram cotton will be harder to carry.
2kg cotton. it doesn't matter what it is as long as you have been given weights
A Kg of anything is the same as a Kg of someting else- we don't need elementary jokes thank you.
Their mass is the same.
they weigh the same silly
Same. That's an old trick question but feathers were more commonly used than cotton.
Both a Pound of Iron and a Pound of Air weight the same ... One Pound ... neither is 'heavier.'
They weigh the same...One Pound.
Yes, silver is heavier than iron. One atom of iron has a mass of 55.85 amu (atomic mass units). One atom of silver has a mass of 107.87 amu. All of this information is easily found on a periodic table.
they weigh the same silly
They both weigh the same, 1 kg
Same. That's an old trick question but feathers were more commonly used than cotton.
The weight of a body in air is its apparent weight because the body body remains immersed in air . Therefore apparent weight of 1kg cotton and one kg iron is same .But volume of 1 kg cotton is greater than the volume of 1 iron
Both a Pound of Iron and a Pound of Air weight the same ... One Pound ... neither is 'heavier.'
They weigh the same...One Pound.
Nooo, 1kg gold is heavier 1kg cotton, because the last one has much more volume than the first, so Archimedes force reduces weight of a cotton more!
Their mass is the same.

Density is mass divided by volume. If we assume the mass of the iron and the cotton is the same, you will find that the iron will occupy less space (less volume) than that of the cotton. The value of a mass divided by a small volume is higher than the value of the same mass divided by a larger volume. If we assume the volume of both the iron and the cotton is the same, you will also find that the mass of the iron will be higher than the mass of the cotton. The value of a large mass divided by a volume is larger than the value of a small mass divided by the same volume. In both assumptions, the value of mass divided by volume for the iron is higher than the value of mass divided by volume for the cotton. Since density is mass divided by volume, the density of iron is therefore higher than the density of cotton.
Due to atmospheric pressure 1 Kg of Cotton is slightly heavier than 1 kg of Iron.According to me cotton will be more lighter as air is a fluid and Archimedes principal applies on it. As cotton occuies more volume it will feel more upthrust and more loss in weight. Therefore it if lighter.
use the ruler as a simple balance and put an iron bar at each end. if they are the same, the ruler will not tilt and the heavier bar must be the third one. If they are different, then the heavier bar is the one that tilts the ruler down.
