Its time to dig your mind hard and answer this question.. What will weigh more 1 kg of iron or 1kg of cotton ? Although the weight is same there has always stayed a debate on this one and you always find contradictory answers. I am also little unsure what to say but I feel 1 kg of iron will be little difficult to lift then 1 kg of cotton so I will say 1 kg of iron will weigh more than 1 kg of cotton.. Let me see what you have to say on this..

i think theoretically, the weights are the same...but maybe if you try to lift them, psychologically, u'll feel that the iron is heavier. however, it still depends on the persons who are lifting, it may be different. but trust me, the weight are still the same. no different at all.

Reminds me of the question. Which has more calories, ice made with hot water or cold water? LOL

1 kg is 1 kg no matter what it consists of.....they weigh the same.

hello joystick7, since both weigh 1Kg i would say that both weigh equally. we are not talking about equal quantity so the are the same. though people maybe mislead by this since we are talking about iron and cotton but since they weigh the same therefore they are equal.. hehehhe...

well..scientifically speaking..i think cotton will weigh more or so it will seem..in order to get better perspectives let us just increase the weight of each to about 20 kgs.. now the cotton will have more volume so it will be more cumbersome than iron making it harder to pick up(it is easier to pick concentrated mass than distributed mass because of the thing called center of gravity).. so we would feel 20kg of cotton weigh more than iron..

Silly question. You can't be serious with this This sort of question was circulating when I was 5 or 6 and it should only confuse someone who had the mental capacity of a 5 year old.

They both weigh the same but one is dense and the other takes up to much room is this any help .

But....it's a measurement of weight...they would weigh the same....I would have to say though the cotton might be more difficult to carry, ONLY because you would need a LOT more cotton to make up a kilogram....or maybe THAT"S the size of a bag of cotton balls....hrm...I'll check that out when I get home.

You have to look at the weight part of the question not the material part. Someone that looks at 1kg of iron and 1 kg of cotton are going to see that there is more cotton than iron but they weight the same.

1 kg of iron weigh the same with 1 kg of cotton. It is just easy. Though people thought 1kg iron is more heavier than 1kg of cotton it is because they think that cotton is lighter than iron. But hey! Come to think of it. 1 kg of iron is equal to 1kg of cotton. The only difference is, you will only put less iron it is because they are heavier than cotton and you need to put lot of cotton in order to make it weigh 1 kg same with iron. They have the same weight.

Math. Same unit which is kilogram. It weighs the same, no doubt. In solving math, you just need to look at the unit and disregard the spoilers which are invaluable in getting the answer. In this case, they are the iron and the cotton. =]

People tend to say that the iron is heavier because small amounts of iron weigh more than large amounts of cotton. However, if you take 1 kg of both it is both 1 kg and therefor equally as heavy. Allthough the iron will be a lot less and the cotton will be a far larger amount; but they will both weigh 1 kg. I think people might also mistake iron for being heavier because it is more solid, and because they might picture 2 amounts being equilly large. Of course a bag of cotton will be lighter then a bag of iron, if both bags are equally larger. However, there is no limit to how much cotton you can use to make 1 kg; and therefor they will both be filled up as much as possible till both weigh 1 kg. I hope that I have made myself clear enough as English is not my native language and I have the feeling I might have repeated myself on several occaisions.. if I did, please excuse me!

They will weigh the same. But, if you're using iron bars and cotton balls, there would be more pieces of the latter than the former.

both are same .. but the density of the material and the shape of the structure influence the difficulty to lift.. keep posting happy mylotting

I think weight of both iron and cotton would be the same. But because of their volume cotton will look lighter. Iron would be a small piece which will weigh 1 KG, but iron will be a small piece so it will just look heavier but both will be of same size.

hi there. it's the same.. 1kg is still 1kg, irregardless of mater.... except of course in terms of volume. there will be more cotton than nails.

Are you serious? They will both weigh the same. Regardless of what item it is, 1 kilogram of something will always weigh the same as 1 kilogram of another thing. Are you playing games or are you just plain... whatever.

Neither weighs more and none is harder to lift,thay are the same weight.What I think you are speaking to is a quantity known as density which is defined as the mass per unit volume or if you wish it is the number of particles within a certain space.In the case of the lead it is more dense meaning it is more compact.Consequently a kg of lead may fit in a bucket but a kg of cotton may fit in two buckets although because of the space in the cotton it can be compressed.A kg of lead is already compact it cannot be compressed anymore.
