Neither on of them weighs more than the other one. They are both a kilogram. 1 kilogram of steel = 1 kilogram of feathers.
Indeed: On the Earth, even if only by a little, 1 kilo of iron weighs more than 1 kilo of feathers!
The force of gravity drops with the square of the distance, so 10 kg at average feather altitude weighs less than 10 kg at average steel altitude. Although the “gravitational attraction” would be the same at a given location, the steel would “weigh” more on a scale due to the greater buoyant force on the feathers.
It doesn't. Their masses are identical. The only thing that will be different is their volume. Even if you compressed the feathers until you squeezed all the air out, they would still be seven times the volume of the iron.
The answer is, of course, that 1 kilogram of gold is just as heavy as 1 kilogram of feathers. They both weigh 1 kilogram!
A ton is a ton, of course; but bricks have much greater density than feathers, and so we are tempted to think of them as heavier (Figure 11.2. 1). Figure 11.2. 1: A ton of feathers and a ton of bricks have the same mass, but the feathers make a much bigger pile because they have a much lower density.
If you check carefully, both are of the same weight as they weigh but, cotton occupies more space than iron i.e. volume of 1 kg cotton is greater than that of 1 kg iron.
Which is heavier, a bag of 10 kg stone and 10 kg of feathers? Well, the contents of the bags both weigh 10kg. So they weigh the same.
Cotton is heavier by 10 kg.
actually 1 kg of steel is heavier than 1 kg of feathers because the feathers have more volume and thus experence more bouyant force due to the atmosphere.
Weight and Size
larger bag when compared to 1 Kg Sugar bag. This is because Popcorn is lighter than sugar.
The relationship between mass and volume is called density, and measures the amount of mass that fits in a given volume. Water has a density of 1 kg /L, that is, 1 liter of water has a mass of exactly 1 kg.
Extreme density
Tungsten carbide is heavier than lead, and almost twice as dense as steel. This enables us to pack extreme mass into a compact, comfortable and agile slide.
1kg of steel is slightly heavier than 1 kg of feathers. 1 kg of feather will displace more air as the density of feather is very less comparitively. More the volume displaced more is the upthrust and less the apparent weight.
Precious metals like gold and silver are measured using the “troy” system where there are 12 ounces in a pound. If you normalize everything to mass a pound of feathers is 454 grams and a pound of gold is 373 grams, therefore the feathers are technically heavier.
▶️The answer: Of course, both have the same weight! But iron is denser than feathers. That means the weight is packed into a smaller space, or the feathers are less dense than iron but take up much more space for the same weight.
Many people are familiar with lead (11.3 kg/L), but osmium is twice as dense (22.6 kg/L)! Each liter (about 1/4 gallon) of osmium weighs 22.6 kg (50 lbs). For comparison, each liter of water weighs only 1 kg (~2.2 lbs). Some other heavy metals include tungsten and gold (19.3 kg/L), which are almost as dense as osmium.
Porous, 3-D forms of graphene developed at MIT can be 10 times as strong as steel but much lighter.
Mercury is the heaviest liquid.
Since the oil is lighter, it is less dense than water and floats on water.
One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. It follows, therefore, that 1000th of a litre, known as one millilitre (1 mL), of water has a mass of about 1 g; 1000 litres of water has a mass of about 1000 kg (1 tonne or megagram).
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.
One kg sand is denser than 1 kg cotton because density = mass/volume. The volume required by cotton is more than the sand and density and volume are inversely proportional.
Solution : (a) A cricket ball is heavier than a water bottle.
Answer. 1kg salt and 1kg cotton Both are same .
