maybe mostly no! but it depends...:D
Yes
A pencil, a piece of paper, and a scientific calculator all have a mass less than one kilogram.
Yes 1 kilogram = 1000 grams 1 gram = 0.001 kilograms
The sawdust. Density is the property that relates mass and volume (density = mass/volume). So the more dense something is, the less space a fixed mass of that material will take up. As iron is considerably more dense than sawdust (or any solid wood for that matter) it will take up much less space.
A change in mass would also change the level of density. If the level of mass in an object went down, it would make the object less dense. Anything that is less dense can move faster. Example: Think of someone cutting a pizza in half and keeping one half of it. A half pizza's mass is less than a whole pizza. You can move a half of a pizza easier than you can move a whole pizza, which is how it affects the movement.
You would weigh it using a mass balance.
yes
Since kilograms are the unit we use to measure mass, the answer is no: both have 1kg. of mass. :D
Please note that a kilogram is a unit of mass - NOT a unit of weight. And yes, a pencil has a mass that is considerably less than a kilogram. For comparison, a kilogram is the mass of a liter of water.
Foam has more volume per mass than gravel.
Mass is measured in kilograms, and you can have a kilogram of any given substance.
It's more mass. It may or may not be physically larger, depending on the density.
One kilogram of mass weighs a tiny bit more than 2.2 pounds on earth, but the same kilogram of mass weighs less than 2 pounds on Mars or the moon.
A kilogram of sand takes up much less space than a kilogram of feathers because sand is denser than feathers. Density refers to how much mass is contained in a given volume. Since sand particles are heavier and more compact than feathers, they occupy less space for the same mass.
Butter has greater volume than lead because butter has more mass.
Yes, if you mean kilometer not kilogram a kilogram is a unit of weight/mass
Yes. 1 kg = 1,000 grams
Nothing would, because "kilogram" is a unit of mass, not weight (force). One kilogram of mass weighs 9.8 newtons (2.205 pounds) on Earth, but it weighs something different in other places. One kilogram is roughly the mass of 34 fluid ounces of water, and it's 10% more than the mass of a 2-pound block of cheese.
