It depends how much feathers and how much nails are in each bag
No. The mass of one liter of feathers is not greater than the mass of 1 liter of nails. The mass of 1 liter of nails is greater than the mass of 1 liter of feathers. That's why 1 liter of nails is heavier than 1 liter of feathers.
No, they are equal: 1 pound = 1 pound.
It is rather a trick question. People are thrown off by the feathers (light things) and nails (heavier things) but pound are pounds. The pound of feathers will most likely be larger in volume than the pound of nails.
The nails and feathers are tied for heaviest, and the gold is lighter than either of the others. The reason for that is the fact that gold is weighed in a different kind of pounds. The 'troy' pound has only 82% the weight of the 'avoirdupois' pound used to measure almost everything else. If they were all measured in the same kind of pounds, then they would all have the same weight.
No. They are equal mass as they both weighed a pound.
It keeps them warm silly head... Feathers are also much lighter than fur and are more aerodynamic (streamlined).
Dogs don't have feathers mainly because they're mammals. Birds (which are not mammals) have feathers because they're lighter and more aerodynamic than fur, making it easier to fly, but fur is warmer than feathers, meaning that it's useful for mammals.
It depends on what substance you are measuring, 383feet3 of feathers will be a lot lighter than 383feet3 of lead
For the most part, kiwi feathers are brown. Some are darker or lighter than others, depending on species, and most are also speckled with white or lighter flecks. Most also have lighter faces and underbellies. The North Island Brown Kiwi, for example, has a thick covering of shaggy, hairy, brown-grey feathers, while the Great Spotted Kiwi, also known as the Great Grey Kiwi, varies from grey to light brown in colour, but its feathers are covered with black spots.

They both weigh the same amount because they are both a pound, and they should both feel about the same, too.
Because lighter and heavier refer to an objects weight - which has nothing to do with density ! For example - a kilo of feathers is heavier than half a kilo of lead - but lead is more dense !
