A kg is a kg so they are the same.
This riddle only works for a pound of gold and a pound of feathers
Precious metals such as gold are measured in troy weight. A troy pound is 12 troy ounces, and each troy ounce is 480 grains, making a total of 5760 grains to the pound of gold.
Most materials use pounds and ounces from the avoirdupois system, and such a standard pound is made up of 16 ounces, where each ounce is 437.5 grains, making a total of 7000 grains to the pound of feathers.
All this means that a "pound" of feathers (or bricks, or lead) is heavier than a "pound" of gold.
Neither. They both weigh 1 pound.
Since one Kg of iron is much more dense (the weight is concentrated in a smaller area) than cotton, it takes up less space.
No. They weigh the same (each weighs a pound). The difference is their densities because a pound of iron has got a much smaller volume than a pound of feathers.
A kilogram of silver weighs more.
It depends which ton you use. In the UK 1 ton = 1 long ton = 2240 lb → a ton of steel weighs more than 2000 lb of cotton. In the US 1 ton = 1 short ton = 2000 lb → both are the same (A "metric ton", or "tonne" is 1000 kg which is approx 2205 lb, a little less than 1 long ton.)
A pound of any substance, material or "stuff" weighs the same as a pound of anything else. A pound is a pound, whether it's cotton or nails.
Both 10kg of cotton and 10kg of iron weigh the same, as they both have a mass of 10kg. The difference in the amount of space each material occupies may make it seem like one weighs more than the other, but in terms of weight, they are equal.
1 kilogram is 1 kilogram no matter what the substance.
Last answer: "Depends of how you weigh them. A ton of cotton could weigh more than a ton of nails." Not true! A ton (2000 lbs) is just a ton. 1 thing that weighs exactly 2000 pounds, cant weigh more or less than another thing that weighs exactly 2000 pounds. This is very simple! How did you get this wrong? Or maybe he/she was referring to the fact that there are at least 3 different types of tons. I am not sure. Well anyway, the point is that they were wrong, and the question now has a correct, acceptable answer. :P
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.
they both weigh the same
All kilograms have the same weight, as long as they're all on the same planet. (We don't know what that weight is until we know what planet they're on.)
one liter of iron
Due to atmospheric pressure 1 Kg of Cotton is slightly heavier than 1 kg of Iron.According to me cotton will be more lighter as air is a fluid and Archimedes principal applies on it. As cotton occuies more volume it will feel more upthrust and more loss in weight. Therefore it if lighter.
Because iron is much more dense.
No, cotton has a density of 1.54-1.56 g/cm³ while iron has a density of 7.874 g/cm³
Iron weighs more than feathers. Iron is a dense, heavy metal, while feathers are light and fluffy. However, if comparing the same volume of iron and feathers, they would weigh the same due to the concept of density.
