Why does a kg of sand take up less space then a kg of feathers?
Because sand is a more dense substance than feathers - it has a larger mass-to-volume ratio.
Describe why one kg of iron in comparision to one kg of cotton takes less space?
Since one Kg of iron is much more dense (the weight is concentrated in a smaller area) than cotton, it takes up less space.
What has more mass 1 kg of lead or 1 kg of feathers?
Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
What has more mass 10 kilograms of feathers or 6 kilograms of lead?
10 kg is greater than 6 kg. kg is the unit of mass. Hence feather has more mass than lead in this case.
Which has a higher density a kilogram of sand or a kilogram of feathers?
Sand. Density is mass / volume. So a higher volume will equal a lower density. Clearly a Kg of feathers will (normally) take up more volume than a Kg of sand therefore the feathers are less dense. You could think of it this way: density is measuring how close together the atoms in a substance are. When the atoms are closer together they take up less volume and the substance is more dense. If you put a Kg of feathers in a box, the feathers would not all join together perfectly meaning that there would be gaps between feathers and therefore the volume taken up by the feathers is greater. You could prove this by trying to push your hand through the feathers. You would be pushing through partly air (which is a mixture of gases and the atoms in a gas are further apart than in a solid) so the task would be easier. It is like comparing pushing your hand through a solid and pushing your hand through solids separated by gas. The latter is easier because there is some "room" for the atoms in the solid to move in to and thus for the feathers to move out of the way of your hand.

Because sand is a more dense substance than feathers - it has a larger mass-to-volume ratio.
Why an iron weight of one kg sinks in water?
Because the iron is more dense; it has more atoms per cubic whatever.
Why does 1kg of lead be less awkward to carry around than 1kg of feathers?
lead is much more dense than feathers, so 1 kg of lead occupies much less space (volume) than 1 kg of feathers
Which is these two is heavy 1 KG cotton or 1 KG iron?
Both are as heavy as each other. however as iron is more dense, it would take up much less space.
What is heavier one pound of iron or one pound feather?
They are both exactly the same - they weigh a pound. However, the feathers will take up a lot more space (about 0.77942 litres for every kg of feathers - or 779 cm3/kg) whereas the lead would be much smaller (about 0.12700 itres for every kg of iron - or 127 cm3/kg).

Why would 1 kg of lead be less awkward to carry around than 1 kg of feathers?
Although they both weigh the same, the kg of feathers would be much more unwieldy, due to its volume. If the feathers were being carried in an open container, on a windy day, when you reached your destination, you would most likely have many less feathers than when you started!
Which is heaviera kg of stones or a kg of feathers?
It's a trick question relying on your preconception that feathers are lighter. They of course weigh the same a kg of versus a kg of. Of course it will take a heck of lot more feathers.
How are the density of wood and iron the same?
iron is more dense then water and wood is less dense then water. iron sinks because it is heavier then the density of water. wood sinks because woods density is lighter then the density of water.
Which is more dense diamond or iron?
Diamonds have a density of 3.51gm/cm3. Coal has a bank density of approximately 1346 kg/m³ (84 lb/ft³). Bulk density typically runs to 833 kg/m³ (52 lb/ft³).
What has more mass 1 kg of lead or 1 kg of feathers?
Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
What has more mass 10 kilograms of feathers or 6 kilograms of lead?
10 kg is greater than 6 kg. kg is the unit of mass. Hence feather has more mass than lead in this case.
