The so-called weight of wood is actually considering the background energy of space, that is to say, although the vacuum does not contain matter, its energy is not zero, and the mass-energy equation corresponds to a certain mass. So the wood is heavy.
However, this difference is too small to be considered if it is not specifically studied on this issue.
-
If you consider air buoyancy, because: buoyancy = liquid density gravitational acceleration discharging volume, so in the air, it should be wood occupies a larger volume, and the buoyancy is also larger, and if the wood weighs the same as steel when the buoyancy is greater than that of steel, the real mass should be greater because it should be wood.

This has something to do with the general theory of relativity, and you should know a little bit about it. Guangxiang proposed that time and space are all matter, which is a new view of time and space. It's a bit hard to accept.
In addition to having its own measurable mass, matter has a small part of the mass to "make" its own space. There is no truly "empty" space, space is a special way of existence of matter, and without matter there is no space and time.
-
In the air is the same weight. But in a vacuum it should be wood heavy. Because a ton of iron and a ton of wood are subject to the buoyancy of the air in the air, the volume of wood is large, and the buoyancy is also large, and the weight we weigh does not consider the buoyancy factor.
Therefore, it can be known that there is no buoyancy of air in the vacuum, and the wood should be heavier.

There's a lot of scientific impurities that are nonsense, and I've seen a lot of similar ones, which are magical and tempting, but if you think about it, you can find the ridiculous contradictions. In this regard, it is better to read the textbook, although there are many things that have been revised and inaccurate, but the definition is generally internationally unified and very accurate, so I still think it is the same.
-
In other words, the mass of the air discharged from the wood is relatively large, right?
mg = weight - buoyancy That's what you probably mean.
-
You make steel into steel sheets, and it's not bigger than wood, pigs, and you weigh it the same as it.

1.Equally heavy.
2.The wood is heavy because it rains and the wood absorbs water.

A ton of iron weighs as much as a ton of wood. Because both substances are the same tonnage, it is not said who is heavier than whom. They are equally heavy.
-
The same weight is a unit of weight, so the weight must be the same, but there may be some differences in size.
-
Equally heavy. Because the ton is a unit of weight, so if they are all one ton of things, then they weigh the same.
-
The same weight because the units of these two things are the same, and both of these things weigh heavily.

For many people, this question seems simple, some may be heavier than a ton of iron, and some people will say the same weight, but the correct answer is not like this.
This question is actually not difficult to solve, and mastering junior high school physics knowledge is enough to understand and solve.
A ton of wood and a ton of iron can be said to be the same weight, or it can be said that a ton of iron is heavier, and it can be said that a ton of wood is heavier.
If we put two scales on the ground, put wood and iron respectively, and add them until both scales show one ton, then most people may think that the mass of wood and iron is one ton, but in fact, the mass of wood is larger, that is, the ton of wood weighed by the scale is heavier.
So why is this weighing of a ton of wood heavier?
This is because the mass of wood and iron we add to the scale is greater than a ton due to the influence of air buoyancy, but because the density of wood is smaller, that is, the volume is larger, the effect on air buoyancy is greater. Therefore, the ton of wood weighed is heavier.
When it comes to air buoyancy, this force is a force of the same nature as the buoyancy of water against the boat. (It can be understood according to the story of Archimedes who used buoyancy to measure the gold content of the crown.) )
When we consider which weight is heavier by artificially removing the effect of air buoyancy, we can assume that two scales are placed in a glass cover in a vacuum (i.e., without any air), or wood and iron are added to the scales, so that both scales show one ton, so that the mass of wood and iron is one ton, and because the acceleration of gravity is g, wood and iron are equally heavy.
The first two experiments were to measure whether the mass of wood and iron was one ton by the number of the scale, this time the mass of wood and iron weighed in the vacuum was taken out of one ton of wood and iron, put on two scales in the air, observe the number, the scale will show that the mass of wood and iron is less than one ton, and the mass of wood is smaller than that of iron, then it is considered that one ton of iron is heavier. This is because in the air, under the influence of air buoyancy, the volume of a ton of wood is larger, making the weighing scale for putting wood smaller, i.e. lighter than iron.

One side of wood is equal to 4, 9 tons indefinitely.
One side of wood is equal to 4, 9 tons indefinitely.
Because it is different from the variety of wood and with the moisture content. Such as fir 4kn m; Quercus glauca (楮木), oak (oak wood), press tree, casuarina 8 9 kn m, so you can answer 4 9 tons of uncertain.

Analysis: Both iron and wood are 1 ton, so they are equally heavy Because both iron and wood are 1 ton, 1 ton of iron is as heavy as 1 ton of wood; So the answer is: Comments:
This question examines the comparison between 1 ton of iron and 1 ton of wood, don't be fooled by their superficial phenomena, since the mass is 1 ton, it means that the same weight, due to the different densities, 1 ton of wood is larger than 1 ton of iron

Can't calculate. Different woods, one side has different weights.

Everyone knows this question for jokes, and the vast majority of people will answer the same weight, because it is the same 1 ton mass; Some people don't want to think about it, so they directly answer that a ton of iron is heavier, which often causes everyone to laugh; If someone answers that a ton of wood weighs, then everyone will laugh even harder, this argument seems to be unfounded at all, but strictly speaking, this answer is indeed correct! The problem is that Archimedes' principle applies not only to liquids, but also to gases. According to this principle, the weight that each object "loses" in the air is equal to the weight of the same volume of air (in layman's terms, the weight of the same volume of air as the object) that is discharged to the object.
Wood and iron, of course, lose part of their weight in the air, and the real weight of their actual weight must be added to it. Thus, in this subject, the actual weight of the wood is equal to 1 ton plus the weight of the same volume of air as the piece of wood, and the actual weight of iron is equal to 1 ton of iron plus the weight of the same volume of air as the piece of iron. However, a ton of wood occupies much more volume than a ton of iron (about 15 times that of iron), so the real weight of a ton of wood is greater than the real weight of a ton of iron!
To be more precise, a ton of wood in the air is really heavier than a ton of iron in the air. A ton of iron occupies a volume of about 1 8 cubic meters, while a ton of wood occupies about 2 cubic meters, and the air expelled by these two objects is about different, that is, in fact, a ton of wood is heavier than a ton of iron.
-
The same tonnage of wood weighed on the earth, because the volume of wood is much larger than that of iron, and the buoyancy of the air is also greater, so after removing the air buoyancy, the wood should be heavier (such as in a vacuum).
-
Of course, it's the same weight, but the volume is different.

Summary. 1 cubic meter weighs about 900 kilograms. The specific gravity of commonly used wood, one cubic meter of rigid wood is equal to the weight of tons:

Expand for you. The head of a poplar tree is about a ton or so wide. Poplar color is white, less resin, easy source oak bleaching, is an excellent raw material for making wood pulp, which can take into account the yield, bleaching and strength, and can make wood pulp and chemical pulp.
Depending on the density of the wood, the weight of the wood of different materials will not be the same, most of the wood weight of the field is less than 1 ton, this is because most of the dry wood will float in the water before renting, if my answer to the question is helpful to you, I look forward to your praise, your support is the driving force for my progress.
