they weigh the same silly
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 weight of the objects is not provided, so it is impossible to determine which is heavier based on the information given.
I don't know what "appears heavier" means. A kilogram of mass is a kilogram of mass. Appearance has nothing to do with it. The cotton is (probably) less dense than the iron and will occupy a larger volume, but that doesn't have anything to do with the vacuum part.
Cotton wool. 2kg of anything is more than 1kg of anything.
Both are as heavy as each other. however as iron is more dense, it would take up much less space.
They both weigh the same, 1 kg

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
Their mass is the same.
Cotton wool. 2kg of anything is more than 1kg of anything.
Since one Kg of iron is much more dense (the weight is concentrated in a smaller area) than cotton, it takes up less space.
Both are as heavy as each other. however as iron is more dense, it would take up much less space.
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.
Both cotton and iron will weigh the same in a vacuum because weight is determined by the mass of an object and gravity. Each object weighs 1 kg in this scenario, regardless of the environment.
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).
