The have the same weight.
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.
Both 1kg of iron and 1kg of cotton would have the same weight in a vacuum. Weight is determined by mass, which is the same for both objects in this scenario.
If there was no wind resistance they would both hit the floor at the same time... however, and since such an atmosphere doesn't exist, (Wind resistance acting on cotton is greater because it has a greater surface area..) so iron will fall faster ... .
1kg of iron contains more matter and occupies less space than 1kg of cotton. Iron is denser than cotton, so it has a higher mass-to-volume ratio.
Cotton wool is less dense than iron, meaning it takes up more space for the same mass. Iron is much denser and therefore occupies less volume compared to the same mass of cotton wool.

Iron (the element Fe) is weighed in units of mass such as the gram, ounce (pound, ton) etc.

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
Usually, cotton cloth is pressed with an iron.
From best to worse, it would be glass, plastic, cotton and iron.
Cotton wool is cotton. Removing it from cotton wool depends on the state and size of the iron involved. Large chunks could be picked out of the cotton. Smaller pieces would fall out during the carding process.

Iron is weighed on an analytical balance because it provides precise measurements down to very small increments, allowing for accurate determination of the iron's mass. This is especially important when working with small amounts of iron or when needing to measure its mass with high precision for experimentation or analysis.
No, cotton has a density of 1.54-1.56 g/cm³ while iron has a density of 7.874 g/cm³
Yes - best with a steam iron for smooth crisp results
