MTL - Rebirth 2002: Nano Life-v5 Chapter 20 Chen Yizhe's demon
"But according to what you said, isn't this a form of the second type of perpetual motion machine?" Song Feier asked suddenly.
"Looks like I'm still learning with hard work these days!" Chen Yizhe raised his brows and said.
"Of course, if you don't study hard, how can you keep up with your footsteps." Song Feier said, and then analyzed, "Take the cooling air conditioner as a distance, the heat pump input power is 1500W and can produce 6000W of heat at the same time, if the device you invented really It can absorb energy from the air, that is to say, if the efficiency of absorbing energy can reach more than 25%, can this heat pump operate independently? No power supply, only hot air from the outside is needed!”
"Should you know about He Entropy?" Chen Yizhe asked.
Song Feier nodded, and then said, "I am more interested in entropy, after all, this is a physical law that has made mankind more and more desperate in history!"
"I can't see at all that you will despair!" Chen Yizhe said speechlessly.
"Because my negative emotions are basically on Black Widow's side!" Song Feier laughed.
Chen Yizhe actually knows that what Song Feier said is also true, just as Marx said: Humanoids have been striding towards the grave since the day they were born. This is a constant law, and entropy is called "irreversible" in science. The inevitability of entropy increase".
In 1854, a German named Clausius put forward a novel concept - "entropy", that in "isolated system, the thermal motion of molecules will always be from the original concentrated, ordered arrangement state. Gradually to a decentralized, chaotic disordered state, the entropy always increases in the spontaneous process of the system from order to disorder.
When entropy reaches its maximum value in a closed system, the system is in a state of energy conservation and resembles a heat-dead state. "Entropy" is the core concept of the second law of thermodynamics, and another meaning of the second law of thermodynamics, with the appearance of equilibrium, the increase of entropy is irreversible.
As long as you understand the law of entropy increase, you will think of a picture, the rapid development of science and technology, let human beings begin to walk out of the earth, out of the solar system, out of the Milky Way, however, with the increase of entropy, each galaxy will eventually perish, and finally There is only the last human civilization left in the vast universe, and this civilization can only surround the last red dwarf star in the universe and build the last Dyson sphere. The star slowly dimmed.
try{mad1(\'gad2\');}catch(ex){} The law of entropy increase reveals the essence of the evolution of the universe, sever everyone's illusion of the eternal universe, and doomed the fate of time and space to avoid the final trend of extinction! This is why people feel hopeless.
Chen Yizhe looked at Song Feier and continued, "In layman's terms, the principle of a heat pump is equivalent to using high-quality energy to absorb heat from a low-quality heat source, and finally obtain medium-quality energy, that is, air conditioning hot air. This is actually to reduce , the process of increasing entropy. According to the third law of thermodynamics, the process of increasing entropy is irreversible.”
"You yourself said that the process is irreversible, so what is the matter with this device that you developed to absorb air heat?" Song Feier asked.
If you really want to create a device that absorbs the heat of the air as Chen Yizhe said, according to the principle of the second law, this process must consume more energy in a higher form.
"When it comes to entropy increase, it is inevitable to mention Maxwell's demon!" Chen Yizhe looked at Song Feier's puzzled expression and knew that she didn't know what Maxwell's demon was.
"I know Maxwell, what the **** is Maxwell's demon?" Song Feier asked.
"This is not a ghost, but a hypothetical demon in physics that Maxwell imagined in order to illustrate the possibility of violating the second law of thermodynamics, capable of detecting and controlling the motion of individual molecules! Maxwell once humorously assumed a 'demon' that could A certain order and rule assigns random thermal motion particles to a certain phase," said Chen Yizhe.
"Listen to you, this hypothetical 'demon' should also consume energy to detect and control the movement of molecules, right?" Song Feier said the key point at once.
"Well, this is an example of the second type of perpetual motion machine. It ignores the energy required for judging the operating state of molecules and the energy required for control, so many people think that this model is impossible." Chen Yizhe replied.
When Maxwell first conceived of Maxwell's demon, it was not really to challenge the second law of thermodynamics, but only to explain that the second law of thermodynamics can only be used for "big objects" in the macroscopic world, and there must be some in the microscopic world. An energy control mechanism for entropy resistance.
"You must not be among the many people, right?" Song Feier said with a smile.
try{mad1(\'gad2\');}catch(ex){} Chen Yizhe nodded, "'Demon' does need to consume energy and increase entropy to monitor molecular motion, but if the result shows that the entropy of the entire closed system decreases at the end What if the entropy increased more than the 'demon'?"
"That shows that there is indeed the existence of Maxwell's demon, and it also shows that the increase in entropy is reversible, and the second law of thermodynamics can also be reversed!" Song Feier said excitedly.
"It's not the reverse~www.novelbuddy.com~, but just like Newton's law only applies to the motion of macroscopic objects, and the same second law of thermodynamics only applies to the macroscopic world! Of course, on the premise, there must be a 'demon'." Chen Yizhe laughed.
"Where's your demon?" Song Feier smiled.
"Here!" Chen Yizhe opened his right palm.
I saw that a small whirlwind suddenly appeared in Chen Yizhe's palm, and the whirlwind became bigger and bigger, and finally became the size of a fist, and finally disappeared without a trace.
Song Feier looked dumbfounded and asked Chen Yizhe, "How did you do this?"
"Isolate and control the molecules in the air clockwise according to the intensity of the molecular motion. The more the gas is controlled, the greater the clockwise temperature difference. Once the control of the molecules is released, these low-entropy ordered The particles will suddenly become high-entropy disordered particles!" Chen Yizhe explained.
For Chen Yizhe, nanoworms are the "demon" of the microscopic world. They can control the particles in the microscopic world. They are small in size, intelligent and have amazing transforming power. Although they are in the process of entropy increase and reversal of the entire closed system, the reduced entropy is only Less than 1%, but it is indeed the existence that can reverse the entropy increase!
Therefore, humans don't even need to despair, because there is still a chance for the eternity of the universe!
This shows the preciousness of nanoworms.
And Chen Yizhe's meteorological weapon is actually the process of implanting nano-worms into energy absorption devices to increase and reverse the entropy of air or seawater, and then convert it into electromagnetic field energy through the heat difference, and transmit it to Dream Valley, and Dream Valley Here, the relay energy will be converted into electrical energy or other energy through the receiver!
