Originally published as Love 105 degrees of you ~ wait! Why 105 degrees? /Super Idol's smile is not as sweet as yours/ /The sun at noon in August is not as bright as you./ /You who love 105 ° C drop pure distilled water/ Have you heard the song "Love You at 105 ° C" recently? After listening to it, I found that its melody kept buzzing in my ears like a bee, lingering and playing in a loop. But when I listen to it, I feel something is wrong. Wait Why 105 ° C? At this moment, the painful memories of learning chemical principles many years ago began to pour out from the depths of memory. Distilled water at 105 ° C does not seem to be so simple! We all know that the boiling point of water is 100 degrees Celsius. People with a little scientific knowledge will know that the boiling point of 100 degrees Celsius refers to the boiling point of water at atmospheric pressure near sea level. At high altitudes, the boiling point of water drops, so things are not easy to cook on the Qinghai-Tibet Plateau. Common sense also tells us that the boiling point of water in a pressure cooker is higher than 100 degrees. But why is that? First of all,50l rotovap, we need to understand what is boiling! 100℃ Boiling is probably one of the most common and fundamental physical phenomena. Whether it's making tea or soup, we come into contact with boiling water every day. I don't know if you have ever wondered why the water suddenly starts bubbling when it boils to 100 degrees? To understand boiling, one must introduce the concept of saturated vapor pressure. Saturated vapor pressure refers to the pressure of vapor in phase equilibrium with solid or liquid at a certain temperature under closed conditions. Expand the full text In popular terms,cbd crystallization equipment, at normal temperatures, the atmosphere is actually pressing water tightly into a liquid state. When we heat the water, the water molecules gain energy, until 100 degrees Celsius, the pressure exerted by the atmosphere is not enough to make the water liquid, so the water molecules scramble to become gaseous, rotovap distillation ,thin film distillation, so they boil. Now we know that boiling is actually a process of atmosphere against water, so we can intuitively predict that when we increase the pressure of the atmosphere, the boiling point of water will rise. You can see that when we increase the pressure a little bit, the boiling point will increase a little bit accordingly. 105℃ Using international data, we can calculate that if distilled water is 105 degrees Celsius, then you should be in a pressure cooker with 1.089 atmospheric pressure. 1005℃ You may want to ask at this time-teacher, teacher! I saw on the Internet that you love 1005 degrees. How big is the pressure of distilled water at 1005 degrees? This is a very good question! Let's go back to the picture just now: We can see that above about 400 degrees Celsius (373.85), the gaseous and liquid States of water merge into one state, which is called supercritical fluid. At this temperature and pressure, the fluid will have both compressibility and effusion, as well as the fluidity of the liquid, which has a very broad industrial value. So if you love 1005 degrees, you are actually greedy for your body. At this time, it is impossible for you, whose body composition is mainly water, to become distilled water, but a supercritical fluid with great industrial value. At this temperature, we have to consider the ionization of particles. It's romantic to think about it. If any object is heated to this temperature, it should have broken through the limits of physics,jacketed glass reactor, which is also a contribution to human science.. Huh? With a rest energy of 172 GeV, the top quark is the heaviest elementary particle, followed by the famous Higgs boson. -China University of Science and Technology Graduate Student Association- -Publicity Department- Source | Stone Popular Science Studio Reviser | Lu Heping and Pan Yuchen return to Sohu to see more Responsible Editor:. toptiontech.com
