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.
no, ether way iron is more dense than feathers
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.
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.
lead is much more dense than feathers, so 1 kg of lead occupies much less space (volume) than 1 kg of feathers
Because sand is a more dense substance than feathers - it has a larger mass-to-volume ratio.
Two pounds of feathers are heavier than one pond of steel, but the feathers are less dense than the steel so two pounds of feathers have a greater volume than one pound of steel. Density determines weather an object will float or sink. If an object can float on water it has to be less than 1. If the object is more dense than water than it will sink.
Well, if you say massive there can be a lot of options, massive can be mass, in this case, i think we are refering to mass, so, imagine that you have a pile of rocks against a pile of feathers, if we add more feathers to it, then maybe we can make it massive but in the other hand, you have to think about that a rock, if it is weighted against a lot of feathers, then the rock is massive, why? because only one rock is available to weight more than a lot of feathers
more dense
More Dense.
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 !
