because sand is smaller than feathers and it would take up as

much space with the sand , and if the feathers were there it would

take up more space because its and larger object than the sand

### 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.

### In the orbiting space shuttle you are handed two identical closed boxes one filled with sand and the other filled with feathers How can you tell which is which without opening the boxes?

In order to find out which box contains the sand, you hold the
box in your hands, while you stand with your back against the wall.
Next you would try to push the box away from your body. If the box
id difficult to push away from your body then it must contain the
sand. We know this because sand has more inertia than feathers!

### How many milliliters are there in one kilogram?

A milliliter is a unit of volume. A kilogram is a unit of mass.
So the answer depends on the specific matter's density. A liter of
water weighs one kilogram. Therefore, there are 1000 milliliters of
water in one kilogram. For a denser material, say sand, there are
about 600 milliliters of sand in one kilogram. For a thinner
material, say nitrogen gas, there are about 800,000 milliliters in
one kilogram.

### What get's warmer sand or dirt?

For the same amount of energy it would be about the same.
However, it would also depend on the type of dirt or sand.
Reason:
The smaller the specific heat the less energy required to heat
the object of equal masses but the faster they cool down.
Sand has a specific heat capacity of about 800 Joules/ degree/
kilogram where
Soil is about 800 Joules/ degree / kilogram.
Water has a specific heat capacity of 4200 J/degree/kg
Copper about 390
