Answer» JIN KAZAMA you are right but in that following question there is no specific condition then on what behalf you have given this type of explanation because your explanation consists of terms ,cases and conditions .but what ever it is i would like to become your homework friend and one of the compatitor thanks Jin Kazama Well if you go for a bit more accuracy and practical experience, it is not true!1kg of cotton will weigh slightly less than 1kg Iron. . Here is the explanation.1. Density of cotton is much less than iron.2. Hence the total volume of 1 kg cotton will be much higher than 1 kg iron.3. So 1 Kg cotton will displace more air than 1 kg iron.4. A larger buoyant force will act on cotton in relative to iron. - Buoyant force being equal to the weight of the fluid being displaced.5. Result will be slight decrease in weight.In vacuum both will weigh the same may be you can able to understand my explanation in this case both have same mass but different weight due to there different surface areas the force of drag(frictional force applied by air ) will be less and also relative density of cotton is more and surface area is also more so the force is diverted to a larger area (p=m/a) Both weight are same
