Which has more volume -- a kilogram of gold or a kilogram of aluminum?
A kilogram of gold and a kilogram of aluminum have the same volume because they both weigh the same. Density is the property that determines how much space a substance occupies for a given mass, and because gold is denser than aluminum, a smaller volume of gold will weigh the same as aluminum.
What weighs more 1 pound of silver or 1 pound of gold?
A pound of gold weighs the same as a pound of silver, because they are both one pound. But a block of gold would weigh more than the same-sized block of silver (gold is more dense than silver, so a smaller volume weighs the same).
If you melt 1 kg of lead will it still weigh the same as the original lump of lead?
Yes, the mass of the lead remains the same, so it will still weigh 1 kg. Melting lead changes its physical state from solid to liquid, but it does not change its mass.
Which ways more a pound of feathers or a pound of iron?
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....
Which has a greater mass a ton of lead or a ton of feathers?
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.
