Answer:
One kg of iron is more heavier because it has more density than that of cotton

As surface area of 1 kg cotton is more, the upthrust will be more on cotton than on iron. Hence the weight shown on the weighing machine of cotton is less than it's real weight. Therefore 1 kg of cotton will weigh more than 1 kg of iron when weighed on a weighing machine.
