they weigh the same silly
both are same havier
Due to atmospheric pressure the weight of 10 kg of cotton is grater than 10 kg of iron.
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.
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.
Cotton wool. 2kg of anything is more than 1kg of anything.
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.
Since one Kg of iron is much more dense (the weight is concentrated in a smaller area) than cotton, it takes up less space.
Cotton wool. 2kg of anything is more than 1kg of anything.
The have the same weight.
Both the same 10kg is 10kg no matter what it is made of bricks or cotton wool or wood or sand, and so on ...
1 Kg of iron will hit the ground first. Although both the cotton and iron will experience the same acceleration because of their same masses, cotton will experience more air resistance due to its large size.
