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.
1 kilogram is 1 kilogram no matter what the substance.
They both weigh exactly the same, namely 10kg, but 10kg of cotton would have considerably more volume than 10kg of iron.Both On the earth,weighs same. both will be having different weight ,if you consider cotton on earth and iron on the moon. W=M*g *Also , if you are having precision instrument and if you measure and ironblock and cotton[in loose],loose cotton weighs more (whatever be the amount due to entrapped air!)
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
they both weigh the same
iron
1 kilo of iron
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.
Same. That's an old trick question but feathers were more commonly used than cotton.
