Is chemistry interesting? Fun facts about chemistry?

Chemistry is very interesting, I like chemistry very much, it is very close to life, and those experiments are also very interesting, chemistry can make some things that we can't understand, how fun.

Different people have different opinions, which I think is still very interesting, especially the variety of experiments.

I think it's fun, especially when it's experimenting!

I graduated from chemistry and chose it because I like it very much and I study it well, but I have studied it for four years in college, and it is relatively boring after a long time. In fact, it's a bit annoying to learn anything for a long time, you say.

On summer nights, there is often a kind of turquoise flame in the cemetery, flickering and flickering, very eerie. Many people will be terrified when they encounter these and run away quickly. So what exactly is "ghost fire"?

In fact, there is a lot of phosphorus in the body of humans and animals, and after death, the corpse decomposes to produce a gas called phosphine, which comes out of the ground and burns itself when it encounters air, but this fire is very small, emitting a kind of blue-green cold light, only flame, no heat. In summer, the temperature is high, and it is easy to reach the ignition point of phosphine gas, so there is a "ghost fire".

In the hot summer, people often drink beer to quench their thirst, and when they open the beer bottle cap, they often see beer foaming outward, sometimes squirting out like a fountain, why is this?

In general, there is around 5 grams of carbon dioxide in each liter of beer. When making beer, it is poured into the bottle by a certain amount of pressure. As a result, there is a certain amount of carbon dioxide dissolved in each bottle of beer, and there is a certain void in the bottle, and when opened, as long as it is gently shaken, the gas forms foam and overflows from the beer bottle.

Once you hear about what products contain "chemical ingredients" in your life, do you avoid them? Do chemical reactions exist only in the lab? Isn't studying chemistry boring and boring?

Chemistry is super interesting, "Chemistry is super fun, but you don't know it yet." "Through the explanation of chemical reactions in life, teenagers are interested in learning chemistry.

The author, Weijun Chen, holds a master's degree in chemistry from Tsinghua University in the Twan region, and he has always believed that "chemistry is life". As a result, he wrote a popular science book that is full of fun, close to life and inseparable from chemistry. What is "alkaline ionized water"?

What is the principle of the "negative ion product" that makes people obsessed? Is it true that the "acidity and alkalinity" of the human body can be changed through diet? The author provides detailed answers to these common and in-depth questions.

This book is rich in illustrations, and the language is interesting and interesting, and uses analogies and examples to let your children understand the mystery of chemistry in life. If your child is struggling with chemistry being too difficult to learn, show him this book!

The interesting chemistry questions in life are as follows:

1. In the mountainous areas, it is common to have thick neck disease and cretiny disease, and the doctor recommends eating more kelp and food, and the above patients are lacking in an element iodine;

2. The metal used to make the metal foil used to package cigarettes and candies is aluminum;

3. The melting point of ** is Celsius, and there are many metals with higher melting points, of which it is about 3 times higher than the melting point, and the metal usually used to make incandescent bulb filament is tungsten;

4. The black Li Hong material on the black-and-white vertical photograph is silver;

5、.Many chemical elements play an important role in people's life activities, and without them, people will get sick, such as osteomalacia in children, which is due to the lack of calcium;

6. The lamp made of a certain gas is filled into the quartz tube, which can emit a strong light hundreds of millions of times stronger than the fluorescent lamp when it is energized, so it is called "artificial little sun", and the gas filled in this lamp is xenon.

When I was in middle school, I was a girl, but I was good at chemistry, but physics was very different, which made me and my teacher feel strange.

I don't know if I can learn chemistry well because I really like it and am interested? Or is it because of my chemistry teacher's preference for me? Anyway, the chemical trim that made many girls feel a headache at that time, I did it "with relish".

I just got the book "Chemistry is Super Interesting" by Mr. Chen Weijun, and I feel very kind, maybe I think of the wonderful middle school days.

Chemistry is super interesting, this book takes common phenomena or events in life as examples, with humorous illustrations, to explain the chemical principles behind phenomena or events that we have never thought deeply about, such as atomic structure, nuclear reactions, concentration, pH, redox and so on.

Chemistry is life", in this book, the author turns his imagination of the world of chemistry into a light-hearted and interesting text, showing us the charm of chemistry in another way, and this process does not require you to take out a pen and paper to calculate. At the moment of traditional education, when popular science knowledge has become a tool for college entrance examinations, such an interesting popular science book is indeed very suitable for young people to read.

When explaining that gas is insoluble in water, he mentioned that if the fart can't be dissolved in water, why is there sparkling water, and the carbon dioxide of those carbonated drinks is fused into it, as long as it sways, it will overflow with a piece of the drink, and people will involuntarily burp and run out by themselves after drinking?

When it comes to real gold, it is not suitable to be afraid of fire refining, because the melting point of gold is only 1000 degrees Celsius, but compared with some other metals, this is also the level of the younger brother, for example, the melting point of tungsten wire can reach 3400 degrees Celsius, otherwise the bulb will not be afraid to use this metal as a wick.

The so-called real gold is not afraid of fire, and it should be understood that no matter how the gold is heated, it will not rust or deteriorate, and it will always maintain its golden appearance, so that it is appropriate.

In this way, chemistry is not boring, and it is indeed closely related to our lives. "Chemistry is Super Interesting", extracts the chemical knowledge in life, and explains these chemical knowledge very humorously, so that I will no longer be afraid of chemistry, and even fall in love with chemistry.

Chemistry is not only fun, but also very practical, and using it well will enrich everyone's life!
