The same. 1 pound = 1 pound.
Both a Pound of Iron and a Pound of Air weight the same ... One Pound ... neither is 'heavier.'
No a lb of bricks and a pound of feathers is still a pound same with concrete and iron
Precious metals like gold and silver are weighed using the Troy system where there are 12 Troy ounces in a Troy pound and each oz. consists of approximately 31.1 grams. Most other items in English-speaking countries are weighed using the Avoirdupois system where there are 16 Avoirdupois ounces in each Avoirdupois pound and each oz. consists of approximately 28.35 grams. Consequently, a Troy pound = 373.2 grams and an Avoirdupois pound = 453.6 grams. So, an ounce of gold is heavier than and ounce of iron, but a pound of iron is heavier than a pound of gold.
Same. That's an old trick question but feathers were more commonly used than cotton.
Iron is heavier because iron is a metal and metals are heavier but silica is not a metal so silica is lighter than iron.
Iron fillings are heavier.
No. Prince Edward Island is famous for potatoes, not potato chips. since we have soil that is so rich with iron it is a great fertilizer, so our potatoes are of the highest quality. We usually ship out our potatoes to Ontario etc to be made into chips. Prince Edward Island only has one potato chip factory left and doesn't ship off island. Hope this helps :]

It has to do to the pounds per sq inch. A 1 pound bar of iron may be the size of a deck of cards while a pound of feathers would have a higher volume and less density. If you compressed the feathers to be the same dimensions as the iron then they should feel like the same weight.
