Feathers are less dense than pennies. A cup of pennies will weigh more than a cup of feathers. A truck load of pennies will outweigh the same sized truck load of feathers. A sports stadium of pennies will outweigh that same stadium full of feathers. Density is the mass per unit of volume of a material. When we compare densities of materials, we compare the mass of a given volume of one material to the mass of the same volume of the other material.
Lead is more dense than feathers. It doesn't matter how much you have of either one. A chip of lead is more dense than a 10-mile convoy of trucks loaded with feathers.
Gold has more mass than feathers. This is because gold is a dense metal, while feathers are lightweight and airy.
No, a ton of feathers and a ton of iron have the same weight because they both weigh a ton. However, the volume occupied by the ton of feathers would be significantly larger than the ton of iron due to the lower density of feathers.
The feathers "take up more room" than the lead. It would be hard to compress the feathers to make them as dense as lead. The feathers have more volume.
That depends on the feather.A new US Penny will weigh approximately 2.5 grams (metric).An ostrich feather might weigh as much as twice that amount.A feather from a canary won't weigh anywhere near as much.A feather from a goose probably weighs less than a penny.
A pound of feathers because feathers are less dense than lead and therefore take up more volume for the same mass.
The gold. The mass per unit volume of the gold will be much higher.
Iron weighs more than feathers. Iron is a dense, heavy metal, while feathers are light and fluffy. However, if comparing the same volume of iron and feathers, they would weigh the same due to the concept of density.
Because sand is a more dense substance than feathers - it has a larger mass-to-volume ratio.
Yes, a bag of feathers can have more mass than a bag of rocks if the bag of feathers is large enough or contains a sufficient quantity of feathers. Mass is determined by the amount of material in an object, regardless of its composition. Therefore, if the feathers are densely packed or if there are many more feathers than rocks, the bag of feathers could outweigh the bag of rocks.
They both weigh the same, one pound. The difference lies in the volume or amount of feathers and concrete needed to reach that weight. Feathers are much less dense than concrete, so a pound of feathers will take up much more space than a pound of concrete.
One kilogram of lead is denser than one kilogram of feathers, so it takes up less space. This makes it easier to carry the lead compared to the same weight of feathers, which would occupy much more volume and be more cumbersome.
