Vol 6 Chapter 17: Conservation mechanical ball

, The fastest update to the latest chapter of the original wizard!
The wizards in the realm of heaven did not understand the source of magic power, and Ace had not yet written the emperor's masterpiece, so controversy about "hot" continued.
Wizards who believe in the theory of biological "vitality" believe that thermal energy may be a supplement to vitality, but it will not be all, because there is magic in this world, and magic has magical effects.
Thomas couldn't explain the magic for the time being, he just steadfastly demonstrated it.
"We need more and more experiments to prove the conservation of'force' in various motions such as mechanics, heat, electricity, acoustics, etc.!"
His eyes are firm, Thomas, who is immersed in experimental research, is not restrained, and some is just fiery research passion.
Donna admired it and said, "We can start with electromagnetics. What is more popular in the magical world today than electromagnetics?"
The two quickly reached an agreement to start experiments with various types of magneto, and many of them concluded a phenomenon.
Donna said in a cold voice: "The motors and circuits in the various tests of Magneto have heat generation. This is the same as the friction phenomenon in the operation of the machine. It is the source of power loss."
Thomas said passionately: "Yes, our experiment starts with the study of the thermal effect of electric current!"
The two people designed an experiment together. To determine the thermal power of a metal wire, they passed the wire through a glass tube and then wrapped it tightly around the tube, leaving a gap between each turn and separating the coil ends.
Thomas then puts the glass tube into a container of water, and uses a thermometer to measure the temperature change of the water after it is energized.
"Thomas, you are responsible for changing wires of different sizes, and I am responsible for changing the current intensity."
Thomas heard Donna's words and nodded. He has prepared more than fifty kinds of wires of various sizes. The two have conducted nearly a thousand experiments in three days, and finally got preliminary results.
Thomas unrolled a magic parchment and wrote a line titled "The Heat Generated by the Metal Conductor of Electricity and the Heat in the Battery Pack During Electrolysis".
He recorded the process of the experiment in detail, and wrote the conclusion at the end, "The heat generated by Blania's current passing through a metal conductor in a certain period of time is proportional to the square of the current intensity and the product of the conductor resistance. This is the Donna-Thomas law. ."
Donna said with satisfaction: "This conclusion looks very simple and mathematical, but we'd better do more experiments to further verify it."
The two did a lot of experiments with electrolytes to prove that the above conclusion is still correct.
The discovery of Donna-Thomas' Law gave the entire Betty Wizard Tower a clear understanding of the role of electric current in the circuit.
Donna imitates the circulation of blood in animals, comparing batteries to the heart and lungs, and electricity to blood. At the end of the paper, she pointed out: "Electricity can be seen as an important medium for carrying, arranging and transforming chemical heat."
It is also believed that a certain amount of chemical "fuel" is "burned" in the battery, and the circuit, including the battery itself, will emit a corresponding amount of heat, which should be as much as the direct combustion of these fuels in oxygen.
Donna said with a little excitement: "The thermal power equivalent is right in front of you. Although we still lack a more critical proof, it already has a direction."
They handed the paper to Betty. Betty was very happy after reading it. She had a hunch that as long as the problem was solved, she might be able to break the limit and become a true mythological wizard.
Betty stuffed the paper into the mouth of a shadowed crow, watched the crow "quack" flying to the central tower, and said with some joy: "Our main task now is to determine equivalence, electricity, elemental energy, Thermal energy and mechanical energy can be transformed and can be equivalent."
This paper is still published in "Magic", all wizards have seen it, Betty Wizard Tower is trying to prove the "thermal power equivalent", such a firm attitude has also caused intense discussions among other wizards, many believe in the theory of "vitality" The wizards also began to modify and improve their theoretical system.
They rooted the focus of the theory on the concept of "magic power" and put forward the hypothesis that everything has magic power. Some people tried to find the current day of the day on the Lich King Witte platform, but Witte publicly stated that they could not prove the vitality theory. .
Witte, who is good at the transformation of life and death and has a lot of experience in biological experiments, said this, and it has cast a shadow on the hearts of many wizards of "vitality" theory.
Betty Wizard Tower, Betty, Donna and Thomas are experimenting beside a group of magneto.
Betty said cautiously: "Exploring the heat loss in the magneto, I believe the natural thing is:
The electric power of a magneto is the same as the current produced by other sources and has the same thermal properties in the entire circuit.
Of course, if we think that heat is not a substance, but a state of vibration, there seems to be no reason to think that it cannot be caused by a simple mechanical action, such as the action of a coil rotating between the poles of a permanent magnet.
At the same time, it must be admitted that no experiment has been able to make a judgment on this very interesting problem so far, because all these experiments are limited to the part of the circuit, which leaves the question whether heat is generated or induced Is the magnetic current transferred out of the coil?
If the heat is transferred from the coil, the coil itself will become cold.
Therefore, we must work to eliminate the uncertainty of magnetoelectric heating! "
After many experiments, they quickly designed a simple and effective experiment. They put the magneto in a water bucket as a calorimeter, rotate the magneto, and lead the current of the coil to the galvanometer for measurement. Water temperature changes.
"The heat generated by the magneto coil is also proportional to the square of the current."
Thomas definitely recorded it.
Donna connected the magneto to the circuit as a load, and another battery was connected to the circuit to observe the internal heat generation of the magneto. At this time, the magneto was still placed in the bucket as a calorimeter. Donna wrote:
"If I turn the wheel to one side, the magneto can be connected to the current in the opposite direction. When turning to the other side, the magneto can be used to increase the current. In the former case, the instrument has all the characteristics of the magneto. The latter case is counterproductive and consumes Mechanical power."
Comparing the experiment of connecting the front and back of the magneto to the circuit, Donna concluded: "We have obtained a medium from magnetoelectricity, with which we can destroy or generate heat with simple mechanical methods."
So far, Betty, Donna and Thomas have determined a law of universal significance from the study of the specific problem of magneto, which is that heat and mechanical work can be transformed into each other, and there must be an equivalent relationship in the transformation process.
They looked at each other, and finally Betty said to Thomas: "You can write down the final conclusion."
Thomas was very moved. He knew that this was taking care of himself, and just wanted to be modest, Donna also said: "Your qualifications still need to be improved, and you have been modest."
With tears in his eyes, Thomas simply sat down and wrote:
"After proving that heat can be generated by a magneto, and the induction force of magnetism can be used to increase or decrease the heat generated due to elemental changes at will, to explore whether there is a constant ratio between the heat and the mechanical work gained or lost, it becomes Very interesting subject.
For this purpose, it is only necessary to repeat some of the previous experiments and simultaneously determine the mechanical force required to turn the instrument.
According to the results of 13 sets of experiments, we can know that the heat that can raise the temperature of a pound of water by one degree is equivalent to the mechanical work required to lift a 838-pound weight by one foot.
Thermal equivalent! "
The magic net vibrated violently, and the power of Da Yuan was surging and cheering, Thomas did not stop writing:
"We can summarize this law as that heat energy can be transferred from one object to another, or it can be converted with mechanical energy or other energy. During the transfer and conversion process, the total value of energy does not change.
That is, when thermal energy and mechanical energy are transferred or converted, the total amount of energy must be conserved. We can call it the law of energy conversion and conservation.
Mathematically, we can state that when the system changes, let the heat exchanged with the environment be Q (heat absorption is positive, and heat release is negative), and the work exchanged with the environment is W (the work done by the environment to the system is positive, The system’s work to the environment is negative), the available thermodynamic energy (also known as internal energy) is
△U=Q+W. "
Thomas has just finished writing, and Da Yuan’s power has poured in like a tiger, most of it has poured into Thomas’ body. He did not hesitate to choose to improve his wizarding qualifications. A large amount of source power made his wizarding qualifications almost instantaneous. Excellent level of overclocking.
Betty and Donna also shared a small amount of energy. Donna was already a golden wizard. Under this impact, she was successfully promoted to a legendary wizard. After a hundred years, she finally caught up with her old sister Blenia.
Betty's state was very fluctuating. She disappeared in a flash and appeared outside the central tower Ais.
After making a briefing, Ace met Betty: "Your state has reached a critical point?"
Betty didn't verbose, and said directly: "Yes, Master Ace, I want to borrow the Scepter of Heaven to assist in the breakthrough state, and I need your dream seal."
Ace's demigod projection nodded, snapped his fingers, and a colorful dreamy flower appeared on Betty's shoulder.
"You can borrow from Witt, and what about your recent series of studies, how about called thermodynamics? The law of energy conversion and conservation just discovered by Thomas is called the first law of thermodynamics!"
Betty had no objection to this, and bowed joyfully and replied, "Thank you for your name."
Before the words were over, she had disappeared. Ace watched her petite back disappear, with a mysterious smile on the corner of her mouth, she returned to her desk.
I saw that Ace pushed aside the masterpiece of the emperor that had just begun, and then unfolded another roll of magic paper and wrote the beautiful flying bird letters.
"Since the first law of thermodynamics appears, can the second be far behind? Will it despair?"
Ace couldn't help laughing, he decided to push hard, and couldn't wait to see the expressions of other wizards.
Betty Wizard Tower, Betty, who just borrowed the scepter of the sky, is holding the scepter. As the day before yesterday, she easily regained the scepter and blessed the power of the entire sky.
The body of her epic wizard has long been semi-sacred, and the soul is in a state of being sacred but not sacred. At this moment, it is directly sacred, and the last bit of savings has been completed.
From the soul to the body, the real longevity has been realized. A little aura is budding from the mind like the world, and it is still so short. She keenly feels that if this line is not available, her longevity state will quickly collapse.
This made Betty's heart a flash, as if thinking of something about thermodynamics.
Too late to grasp the fleeting inspiration, there are more important things now, Betty instantly contacted the dream source, almost screaming: "Dayuan, open personality."
The news was transmitted to Ace Projection in an instant through the great source of dreams. He stopped writing, immediately opened up his personality, and touched his nose: "The habit of shutting down the personality almost failed Betty. It really can't be done without resources. It succeeded, but to a certain extent, the first law of thermodynamics can indeed explain the state of achieving demigods."
Ace lay down and disappeared slowly, appearing in the Betty Wizard Tower.
"I'll help you again. This is a drop of pure divine essence from the body."
A shining gleam in Ace's hand, and a divine essence containing terrifying and orderly energy floated towards Betty, floating above her head.
Betty is at a critical moment. When the essence of divine power comes, her accumulation will be more abundant. In the world of mental images, Betty's mind has clearly seen the true spirit and is one with the true spirit. The entire mental world has turned into chaos and extremely hot flames. The world is surging in her mind.
From the fire element to the phlogiston, from the phlogiston to the oxidation reaction, to thermodynamics, the flame in Betty's heart has not changed.
"'Heat' is the core and drives the machinery. This is my way and this is my cognition.
When thermal energy and mechanical energy are transferred or converted, the total amount of energy must be conserved. This needs to be a closed-loop system, an isolated system.
Demi-God Eternal Life ~EbookFREE.me~ It is precisely because of the great strength that a closed-loop system inside has been successfully constructed. Of course, this system is not completely closed. It needs a switch to communicate with external'energy', but as long as the core is maintained With stable energy, demigods can naturally live forever.
If you map the demiplane from the mental world, you can condense this closed-loop state very well to maintain your own energy conservation. The foundation of my mythology is the "ball of conservation"! "
In an instant, the emptiness of the mental world draws high-quality energy from the outside world, forming a huge fireball in the entire mental world, and then a strange mechanical structure sphere envelops the huge fireball.
The mechanical structure made a creaking sound, and a large number of strange metals grew on their own, quickly completely enveloping the fireball, and the texture of the metal made this mental world gradually dark.
Betty opened her eyes, soared into the sky, disappeared, and he appeared outside the sky, in the wizarding world.
The eyebrows suddenly appeared bright red, like a soldering iron, which suddenly expanded and turned into a huge sphere. Betty twisted hard to separate his head from the sphere.
"This is my half plane, conserving the mechanical ball."
