Which is heavier 1kg cotton or 1kg Pebbles?

Since both cotton and pebbles are of equal mass i.e 1kg, so they both weigh same. so, both 1 kg cotton and 1kg pebbles are of same weight.

Will the weight of 1 kg of iron and 1kg of cotton be the same in air explain?

Answer: density of cotton is less than Iron so it would have more volume. So, 1 kg cotton will displacement more Air particles than Iron.

Is cotton heavier than iron?

ANSWER 2 Iron is heavier because heaviness of an object is determined by its density as the iron has far more density than cotton therefore in reality iron is heavier than cotton.

What feels heavier a kilogram of cotton or a kilogram of rocks Why?

Upthrust will be more for the cotton as it will have a larger surface area per unit of apparent weight due to the lower density. So every 1 kg apparent weight is somewhere near 1.1 kg actual weight of cotton. And 1kg Iron actually weighs near 1.09 Kg. Therefore, Cotton is heavier!

What is heavier 1kg of steel or feathers?

4 Answers. Feathers are made from keratin, with a density of about 1.3 g/cm3. The net volume displaced by a kilogram of feathers is then 751 cm3. Steel has a density of 7.86 g/cm3 and a kilogram of it displaces 127 cm3.

Which is heavier 1 kg of steel or 1 kg of cork?

Answer: Iron being a metal element, and cork being what it is, Iron is much more dense then cork, even if the you have the same weight amount. So the amount/volume you would need to have a Kg of cork would be greater then the amount to make a Kg of iron.

How is cotton heavier than iron?

Which is heavier iron or cotton?

The answer depends on what you mean by the word ‘heavier’ and how you have measured 1 kg. If we assume the true mass of both iron and cotton to be 1 kg, and then measure their weight on a weighing machine, iron will be heavier.

What is the actual weight of cotton in kg?

We are giving an apparent weight of 1Kg for both items. Upthrust will be more for the cotton as it will have a larger surface area per unit of apparent weight due to the lower density. So every 1 kg apparent weight is somewhere near 1.1 kg actual weight of cotton.

Why does cotton weigh more than steel in vacuum?

So if you weigh both steel and cotton, the cotton will displace more volume of air and hence buoyant force will be more in case of cotton, whereas the net force shown will be 1kg in both cases. So if you weigh in vacuum the same 1 kg of steel and 1kg of cotton which you earlier weighed in air, the cotton will weigh more.

How many balls are on each side of a scale?

Don’t answer three. Three is wrong. It’s the tempting answer — weigh all the balls, four on each side. Determine which side is heavier. Then take the heavier group of four and divide them again, two on one side of the scale, and two on the other.
