    Is this pound weighed in vacuum or in air?

    If it is weighed in a vacuum, it will be the same weight.

    If you weigh 1 catty in the air, it is actually heavier cotton.

    Because: the actual mass of the substance in the air = the weighing mass + the buoyancy of the air.

    So the quality of both is actually.

    1 kg of iron + buoyancy of iron], [1 kg of cotton + buoyancy of cotton] The object in the air is affected by air buoyancy, the density of cotton is small, and the volume of cotton of the same quality is relatively large compared with iron, and the air buoyancy is also relatively large.

    So, well. The conditions given in this question are incomplete. There is no right answer and it will be nice to solve the problem for you, hopefully, thank you.

    Theoretically it is the same weight. However, because the cotton is relatively fluffy and affected by air buoyancy, it will cause it to weigh out a catty, but the quality of cotton is greater than that of iron.

    The same weight because the quality is the same. Weight is quality.

    A pound of iron weighs as much as a pound of cotton. According to the title, the mass of cotton and iron is one pound, so a pound of cotton is as heavy as a pound of iron. The density of cotton is smaller than that of iron, so it is the same as a pound of cotton and a pound of iron, and the volume of a pound of cotton is much larger than that of a pound of iron.

    Units of Mass:Mass is one of the seven fundamental dimensions in physics, with the symbol m.

    In the International System of Units, the basic unit of mass is the kilogram, the symbol kg. Originally stipulating that the mass of 1000 cm3 (i.e. 1 dm3) of pure water at 4 years was used, a standard kilogram prototype was made from platinum-iridium alloy and stored in the French International Bureau of Weights and Measures. Since May 20, 2019, a new definition of quantization based on Planck's constant has been implemented for the kilogram.

    Unit conversion: 1t=1000kg; 1kg=1000g;1g=1000mg。

    A pound of iron weighs as much as a pound of cotton. It's just that they're not the same size. The specific gravity of iron is greater than that of cotton, and the volume of 1 pound of iron is about the size of a pear, and the volume of 1 pound of cotton is about the size of a basketball.

    They have a very great effect on human beings, iron can be used to build buildings, make cars and ships, and cotton can be used to make clothes needed by human beings, and oil can be extracted, etc., they are all indispensable things for human beings.

    Cotton becomes the cloth instructionsThe traditional process is to first remove the seed cotton into lint, which is the state that can be used as a warm layer of cotton quilt, and then made into a twist.

    Yarn is spun into a spinning wheel and wound on a shuttle, then on a loom.

    Now the industrial production process is the same, but some auxiliary procedures such as bleaching, dyeing, jacquard when weaving, etc., can make the fabric more delicate and colorful, and also improve the production efficiency.

    Just as heavy! 1 catty = 500 grams.

    One pound of cotton = 500 grams.

    One pound of iron = 500 grams.

    Therefore, their weight is the same, and under the premise of the same quality, the density of cotton is less than that of iron, so the volume of a pound of cotton is much larger than that of a pound of iron. Therefore, many people subconsciously feel that iron will definitely be heavier than cotton, but the weight of both is actually one catty, that is, the same weight.

    Of course it's the same weight, because they all weigh a pound.

    The vast majority of people will weigh the same weight, because they are also 1 pound mass; Some people don't want to think about it, and they just weigh a pound of iron, which often causes everyone to laugh; If someone weighs a pound of cotton, then everyone will laugh even harder, this statement seems to be unfounded, but strictly speaking, this answer is correct!

    The problem is that Archimedes' principle applies not only to liquids, but also to gases. According to this principle, the gravitational force that each object "loses" in the air is equal to the gravitational force of the same volume of air (in layman's terms, the same volume of air gravity as the object) that is discharged to the object.

    Cotton and iron, of course, also lose some of their gravity in the air, and we have to add the lost gravity to their actual real gravity. Therefore, in this problem, the mass of cotton is one catty, but the actual gravity is equal to 5 Newtons plus the same volume of air gravity with a piece of wood, and the mass of iron is also one catty, but its actual gravity is equal to 5 Newtons plus the same volume of air gravity as this piece of iron, but the volume of a pound of cotton is much more than a pound of iron, therefore, the real gravity of a pound of cotton is greater than the real gravity of a pound of iron.

    The first question to ask is what exactly the author means.

    Why do you say that, especially when applying, as long as this kind of question comes up, it is useless for you to answer it. That's all by design.

    According to what we learned during our school days, this kind of problem has been encountered. Ask you which weighs a kilogram of A or 1kg of B.

    It must be based on the quality. The quality is the same, it doesn't matter what it is, it's the same weight.

    But if someone asks you about it, he'll tell you. Such a simple truth, elementary school students know that I will ask you again. I'm making you think deeper. Then he gave Balabala's a bunch of things.

    Like what. You're talking about the ideal. But is it possible in practice?

    In real life, iron and cotton are in the air. We must have told you about buoyancy in junior high school physics. So it says it's a pound, but is it?

    The scale on the g object - the buoyancy experienced = the volume of cotton shown on the scale. Buoyancy = air density multiplied by g multiplied by volume So cotton is more buoyant. So cotton is heavy.

    Or tell you that cotton absorbs water when it is placed in the air. Thou hast weighed it with water. So iron is heavy. Or when you weigh it, the cotton absorbs water again, so the cotton is heavy.

    So whatever you say you are wrong.

    If you follow the above assumptions. He'll tell you again. Ah, whoever makes you think so complicated, often simple things make you think complicated. Didn't the elementary school teacher teach you the same weight? And then a bunch of balabalas.

    So you're not right about that. The key is the intention of the person who asked the question. Then who knows what the person who came out of the question thinks.

    A pound of cotton is the same weight as a pound of iron, cotton is more diligent, a pound of cotton will have a large pile, and iron is heavier, and a pound of iron may only have a small piece.

    A pound of iron weighs as much as a pound of cotton. One pound is equal to 500g, whether it is a pound of cotton or a pound of iron, his weight is 500g. The test here is the concept of weight, many people subconsciously think that iron will definitely be heavier than cotton, in fact, it has been explained in the title that the weight of both is one catty, that is, the same weight.

    In the case of the same volume, the iron will be heavier than the cotton, because the density of the paste is greater than that of cotton, the same volume, the greater the density, the greater the mass, referring to the physical formula "=m v" where denotes density, m denotes mass, and v denotes volume.

    1. The same weight. Weighing in a vacuum, it is 500 grams (one catty), of course, the same weight.

    2. Cotton weight. Under normal conditions, there is air in the middle of cotton, and cotton needs to be counted as air weight, so it is one pound in a vacuum, and under normal conditions, cotton is heavy.

    3. Iron weight. Because the volume of iron is small, the buoyancy of the air is small, and the volume of cotton is large in the air, the buoyancy is large, and of course it is light, so it is one pound in the state of vacuum, and under normal conditions, the iron is heavy.

    Just as heavy!

    The weight of a pound of iron and a pound of cotton is the same, both are a pound, under the premise of the same weight, the density of cotton is smaller than the density of iron, so the volume of a pound of cotton is much larger than the volume of a pound of iron, because cotton is a light object in people's subconscious, so they will feel that iron will definitely be heavier than cotton, in fact, the two are the same.

    Mass unit conversionKilograms = tons.

    Kilograms = 1,000 grams.

    Kilogram = 1,000,000 mg.

    Kilogram = 1,000,000,000 micrograms.

    5. Metric: 1 catty = 10 taels = 100 money.

    6. Municipal system: 1 catty = 16 taels = 160 money.

    Two = kilograms = 50 grams.

    Jin = 10 taels.

    Jin = kg = 500 grams.

    Density

    is a measure of the mass within a specific volume, density is equal to the mass of an object divided by volume, which can be represented by symbols. In the International System of Units and the Chinese legal unit of measurement, the unit of density is kg m3.

    Quality

    It refers to the amount of matter contained, regardless of the change of position, state, shape, the mass of an object will not change, it is the physical property of matter.

    Volume

    It refers to the size of the space occupied by a substance or object, the amount of matter that occupies a specific volume.
