An ounce is an ounce.
they both weigh an ounce so they weigh the same This is not the correct answer...DuFuss. Gold is weighed in troy weight, one troy ounce = 480 grains= 31.2 grams. Brick would be measured in avoirdupois weight, where 1 ounce=437.5 grains or 28.4 grams. Therefore, an ounce of gold weighs more than a ounce of brick, feathers, lead, etc.
Because pounds measure weight. A pound of feathers would be a whole lot bigger than a pound of lead.
They both weigh the same.
They both weigh one pound and are therefore the same weight. The answer to the questions is no.
They all would weigh the same amount, 1 Kilogram.
It both are one ounce then both weigh the same
They are the same. If you're asking about density, though, (how much matter is packed into a certain volume), you can test this by first dropping a pound of iron on your foot, followed by the feathers. An ounce of gold, however, does *not* weigh the same as an ounce of lead. Some research will show why....
Since each substance weighs a pound, they weigh the same amount.
One, the correct term is "Which weighs more: a pound of lead or a pound of feathers?" Two, the answer is that they weigh exactly the same, because they both weigh a pound.
Something that weighs a ton is equal to other things that weigh a ton, therefore a ton of anything is equal to a ton of anything else. Even if it's feathers versus lead or cotton versus cement.
By definition, they have exactly the same mass.
I would need more details to answer but if your asking about the common question, "What weighs more, an ounce of feathers, or an ounce of rocks?" then they are the same.
