Both are equal
Depends if they weigh 1 kilogram where they are or one kilogram compared to Earth's gravitational pull.
~The kilogram technically does not measure weight, it measures mass. If all the items you mention have the same mass then the densest material (iron) has the greatest weight because it displaces the least volume of air. A balloon filled with one kilogram (around 5600 liters) of helium will float in the air. If you want to measure weight, the proper unit is the Newton.
What else can I help you with?
Which has the greater density a kilogram of feathers of kilogram of iron?
Iron has a greater density.
Which is heavier 10 pounds of feathers or 10 pounds of iron?
These two quantities both weigh the same- 10 pounds.
Which takes up the most space a pound of feathers or a pound of iron?
Feathers
Which is have a greater volume 1 kilogram of copper and 1 kilogram of iron?
Oh, what a lovely question! You see, both 1 kilogram of copper and 1 kilogram of iron have the same weight because they both weigh 1 kilogram. However, copper is denser than iron, so a 1-kilogram block of copper will take up less space than a 1-kilogram block of iron. It's all about how tightly packed the atoms are in each material.
What is heavier 1 cubic centimeter of gold or 1 cubic centimeter of iron?
gold it is thre times heavier!
Which has the greater density a kilogram of feathers of kilogram of iron?
Iron has a greater density.
Which is heavier a ton of iron or a ton of feathers?
They are both equal in weight.
1 kilogram feather heavier or 1 kilogram stone heavier?
Due to atmospheric pressure the weight of 10 kg of cotton is grater than 10 kg of iron.
What heavier a kilogram of sawdust or a kilogram of iron?
They both weigh 1kg....... so they weigh the same,
Are iron weights heavier than concrete weights?
No a lb of bricks and a pound of feathers is still a pound same with concrete and iron
Which is heavier 1kg iron or 1kg wool?
Not sure if this is a serious question but...A kilogram is a unit of mass, or in this case, weight.A kilogram is a kilogram.One kilogram of anything is a kilogram.1 kg of iron = 1 kg of wool.
What is heavier a kilo of sand a kilo of iron a kilo of feathers a kilo of flour or a kilo of fruits?
They are equal weight.
Which is heavier 10 pounds of feathers or 10 pounds of iron?
These two quantities both weigh the same- 10 pounds.
What is heavier 1 kilogram stone or 1 kilogram iron?
This is a trick question, right? Regardless of the substance , if they weigh the same, they have the same weight. What is different is the density of sbustances. For instance a cubic foot of Helium weighs less than a cubic foot of carbon dioxide. A cubic foot of iron weighs more than a cubic foot of aluminum. If you visit the web site http://www.chemicalelements.com you can look up the density of many substances that are called elements.
What is heavier iron or silica?
Iron is heavier than silica. The atomic mass of iron is higher than that of silica, which makes iron denser and heavier.
Which is heavier iron filings or seawater?
Iron fillings are heavier.
Is iodine heavier than iron?
No, atomically Iron is a heavier element
