Does wood have a liquid state, and can wood be liquid?

After reading the above, I can't help laughing and crying... Is junior high school knowledge enough to solve practical problems?

First of all, not all substances have gas-liquid-solid states. Most polymer materials, such as rubber and plastics, do not exist in a gaseous state because they decompose before they reach their "boiling point".

There is no liquid state in wood. However, there is no liquid state in either wood or wood. The reason is simple, carbonization begins before the "melting point" is reached. Of course, at high temperatures isolated from oxygen, it is possible for the remaining carbon to melt, but that obviously cannot be called "wood" anymore.

By the way, add to the physical process of liquefaction. Molecules have greater mobility when a substance is in a liquid state, and to change from a solid state to a liquid, the molecules need to gain energy by absorbing heat. The higher the energy required for a substance with a high boiling point, but if the energy required is too great to exceed some of the bond energies of the molecule, then the liquid form will not appear, but a chemical reaction will occur.

to Arithmetic Scholars:

I'm not a kid anymore, I have a bachelor of science in physics, a master's degree in chemistry and materials science, and if the junior high school knowledge you have learned is completely sufficient, it either means that your junior high school education is different from that of mortals, or you don't know how to solve the problems you encounter. Can a substance be called a substance when it is decomposed by heat? I have found a source for every sentence I have said above.

If you think I'm wrong, I'd like to ask you what is the boiling point of PMMA.

I just arrived, and the discussion among the students was very interesting, after all, the discussion makes the real knowledge. Encouragingly.

Well, I'm a PhD supervisor in theoretical physics

The question is actually quite simple, I ask you if you have a liquid state?

The answer is simple, no, because if you become liquid, it's not you.

That classmate should also pay attention

Wood is different from steel, the difference is that if you can ideally think of steel as 100% iron, then it has a melting point, that is, it melts into a liquid state, and in turn, its reverse process is completely valid. Students who are familiar with industrial principles should know that steel is actually made by cooling molten molten steel

If wood also has a liquid state, then good, we heat it, not to mention that it burns with air, we isolate it from the air and put it in a vacuum, that is not good, because students who have studied biology know that wood, in fact, has fiber composition It belongs to the category of organic matter, and heating will destroy the molecular chain structure and spatial distribution, you must know that this is an irreversible process, even if it can be converted into liquid viscous substance, it cannot be reduced. It is important to know that normal protein molecules and BSE softovirus proteins are completely identical in chemical chain structure, and the shape of the knowledge space twist is different, so it becomes two completely different substances, therefore, an irreversible process of wood can not talk about whether there is a liquid state Because the liquid state is no longer wood, it is already some kind of amino acid or sugar

1 Wood is a mixture, some of which are liquid and some are not, and as a whole, there is no liquid wood.

2 Not a substance with one of the three states of solid, liquid, and gas can be transformed into the other two. When some substances are heated, they will undergo a chemical reaction before the melting point and become other substances, resulting in the substance not having a liquid state. This is often the case with polymer organics, and many of the components of wood are.

Timber First of all, think about what was before?

It's a tree, it's a living thing.

What we usually call wood is made up of countless plant cells, therefore.

On the inside of the wood, it's not like steel.

Cells are made up of a variety of different molecules.

Wood and steel are more different than wood and you (both are living beings).

So even if there were liquid wood, which the people said above, it would not be wood in nature for a long time.

So "wood" is not liquid.

The composition of wood can also be explained by "is a living thing".

The basic chemical elements contained in it are basically the same as those of humans, but the content is quite different.

How do you say that? Wood is not liquid, and if wood is said to produce a liquid state after a special reaction, it is no longer wood, it has become oil

Wood is composed of a variety of substances, and if it is a single substance, it will be liquid, but it may not be mixed together

Wood is not a single substance, it has many chemical components.

Each ingredient naturally has a liquid form, but don't expect these ingredients to become liquid together.

Wood is a mixed material, a complex biomass, mainly including lignin, cellulose, hemicellulose, protein and other substances. Wood can be obtained by dry distillation of isolated air heating method to obtain wood essence and methanol. There is also some ash that is solid.

Point out the mistake on the 3rd floor, you said that there is liquid wood for sale anywhere on the Internet, but in fact, it's not, as far as the link address you gave, I looked at it, for example"Liquid xylanase (. "Actually, it is talking about xylanase. "Such as green can be liquid wood"Actually, it's not liquid wood, it's just a malleable material with the properties of wood.

Bachelor of Science in Physics, Master of Engineering in Materials Science in Chemistry, Doctoral Supervisor in Physics.

Wow, pretending to be so many degrees at once, you are really qualified enough.

In the middle of the night, three more people went online, and three numbers were opened for this problem.

Said a lot of nonsense. I would like to point out that you could write a big article.

There's no need to be bored enough to talk to you about this.

Wood is a mixture in which various substances can be melted.

Wood can "become" liquid, but liquid is not wood.

Does that sound a bit contradictory, but let me take my time. Wood is a mixture, the main components are cellulose (40-50%), lignin (20-30%), etc., so it does not have a single melting point. So what happens when you heat wood?

Here are three common answers:

Elementary school student: Wood will burn!

Junior high school student: (Think) If there is oxygen, it will burn, and if there is no oxygen, it will ......Will it melt?

High school student: (Holding up the glasses, remembering the molecular formula of cellulose () Wood burns in an oxidizing environment, and long-chain macromolecules such as cellulose and lignin will pyrolyze to form coke, small organic matter, and possible gas products such as coke, small molecules, and ...... in an oxygen-free environment

Presumably, everyone has also understood that even if the wood is heated in an oxygen-free environment, the macromolecules in the wood will begin to decompose when it reaches more than 350, and the condensation gaseous products can indeed obtain some liquid organic matter, but these are no longer the components of the original wood. Therefore, there is no such thing as "liquid wood" in the strict sense of the word.

Everyone knows that if you heat wood with fire, it will soon turn into a cloud of ashes, so whether there is liquid wood or not, the foreigner decided to prove it with experiments. Scientific Experiments, Physical Principles, Magical Phenomena, Scientific Fun, Interesting Experiments, Challenge Experiments, Strange Experiments, Brain Holes.

Can wood still be melted into a liquid state? Foreigners personally experiment, let's see it together.

Liquid wood. --Has the advantages of wood There are no disadvantages of wood.

With wood fiber powder, carbon fiber powder, ecological plastic powder as the main raw materials, modified by additives, under vacuum, high temperature, high pressure conditions, melted into semi-flowing substances, cooled material not only has the excellent characteristics of natural wood, can be sawed, drilled, nailed, planed, screwed, but also has the chemical stability of high-strength plastics, can completely replace wood, can be widely used in aerospace, automobiles, ships, construction and other industries, can be 100% recycled, this revolutionary man-made material is called " Liquid wood".
