The wizards in the realm of heaven do not understand the source of magic, and Ace has not written the emperor's masterpiece yet, so there are constant controversy about "hot".

Wizards who believe in the theory of biological "life force" believe that heat energy may be a supplement to vitality, but it will not be all, because there is magic in this world, and magic has magic effects.

Thomas cannot explain the magic for the time being, he just firmly conducts evidence.

"We need more and more experiments to prove the conservation of 'force' in various movements such as mechanics, thermal, electrical, acoustics, etc."

His eyes were firm, and Thomas, who was immersed in experimental research, had no restraint, but only had a fiery passion for research.

Donna said appreciatively: "We can start with electromagnetics. What kind of science is more popular than electromagnetics in the magic world today?"

The two quickly reached an agreement and started experimenting with various types of magnetomotors. Many of them summarized a phenomenon.

Donna said in a cold voice: "There are heating phenomena in the motors and circuits tested by magnetomotors. This is the same as the friction phenomenon during the operation of the machine parts, and it is the source of power loss."

Thomas said passionately: "Yes, our experiment entry begins with the study of the thermal effect of current!"

The two jointly designed an experiment. In order to determine the thermal power of the metal wire, they let the wire pass through a glass tube, and then wrapped it tightly around the tube, leaving a gap between each turn, and the coil terminals are separated.

Then Thomas put the glass tube into a container containing water, and after powering on, use a thermometer to measure the temperature change generated by the water.

"Thomas, you're responsible for replacing wires of different sizes, and I'm responsible for changing the current intensity."

Thomas nodded after hearing Donna's words. He had prepared more than fifty types of wires of various sizes. The two of them conducted nearly a thousand experiments in three days and finally got preliminary results.

Thomas unfolded a roll of magic parchment and wrote a line titled "Heat generated by metal conductors of electricity and heat in the battery pack when electrolysis".

He recorded the experiment in detail and wrote a conclusion at the end, "After a certain period of time, the heat generated by Brenia's current through a metal conductor is proportional to the square of the current intensity and the product of the conductor resistance, which is Donna-Thomas' law."

Donna said with satisfaction: "This conclusion looks very concise and mathematical, but we'd better do more experiments and further verify them."

The two of them used electrolytes to conduct a lot of experiments to prove that the above conclusion is still correct.

The discovery of Donna Thomas's law gave everyone in the entire Betty Wizard Tower a clear understanding of the role of current in the circuit.

According to the circulation of blood in animals, Donna compared the batteries to the heart and lungs, and compared the current to blood. At the end of the paper, he pointed out: "Electricity can be regarded as an important medium for carrying, arranging and changing the heat."

It is also believed that a certain amount of chemical "fuel" in a battery will emit heat of the corresponding size in the circuit, including the battery itself, and the result of direct combustion of these fuels ignite in oxygen.

Donna said with a little excitement: "The heat equivalent is near. Although we still lack more critical proofs, it has already become directional."

They handed the paper to Betty, and Betty was very happy after reading it. She had a premonition that as long as this problem was solved, she might be able to reach the limit and become a true mythical wizard.

Betty stuffed the paper into the mouth of a shadow crow, watched the crow fly to the central tower "quack" and said with a little joy: "Our main job now is to determine the equivalence, electricity, elemental energy, thermal energy, and mechanical energy can be converted and equivalent."

This paper is still published in "Magic", and all the wizards saw that Betty's Wizard Tower was trying to prove the "heat power equivalent". Such a firm attitude also caused fierce discussions among other wizards. Many wizards who believe in the "life force" theory have also begun to modify and improve their theoretical system.

They rooted the theory in the concept of "magic" and put forward the assumption that everything has magic. Some people tried to find the contemporary Lich King Witt, the Lich King, to stand on the platform, but Witt publicly stated that he could not prove the theory of vitality.

Witt, who is good at transforming life and death and has a lot of biological experiment experience, said this, which casts a shadow on the hearts of many wizards with "life force" theories.

Betty Wizard Tower, Betty, Donna and Thomas are conducting experiments next to a group of magnetrons.

Betty said cautiously: "I believe it is natural to explore the heat loss in magnetrons:

The power of a magnet motor has the same thermal properties as the current generated by other sources.

Of course, if we think that heat is not matter, but a state of vibration, there seems to be no reason to think that it cannot be caused by the action of a simple mechanical property, 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 yet been able to make a judgment on this very interesting question, because all these experiments are limited to the parts of the circuit, which leaves a question of whether heat is generated or transferred from the coils that induce magnetic current?

If heat is transferred from the coil, the coil itself will become cold.

So, we must work hard to clear the uncertainty of magnetoelectric heat!”

After many experiments, they quickly designed a simple and effective experiment, putting the magnetron in a bucket as a calorimeter, rotating the magnetron, and directing the current of the coil to the amperometer for measurement, while measuring the water temperature change of the bucket.

"The heat generated by the magnetic motor coil is also proportional to the square of the current."

Thomas recorded it with certainty.

Donna then connected the magnet motor as a load to the circuit, and connected another battery to observe the heat generation inside the magnet motor. At this time, the magnet motor is still placed in the bucket as a calorimeter, Donna wrote:

"If I turn the wheel to one side, I can connect the magnet motor to the reverse direction and turn to the other side, and I can use the magnet motor to increase the current. In the previous situation, the instrument has all the characteristics of the magnet motor, while the latter situation is counterproductive and it consumes mechanical force."

Comparing the experiment of magneto-connected circuits, Donna concluded: "We obtained a medium from magneto-electricity, which can destroy heat or generate heat by simple mechanical methods."

At this point, Betty, Donna and Thomas have determined a law with universal significance from the study of the specific problem of magnetomotors, that is, thermal 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 write down the final conclusion."

Thomas was very moved. He knew that this was his care for him. He was about to be humble, but Donna also said: "Your qualifications still need to be improved, and you have been humble."

Thomas was filled with tears in his eyes and simply sat down and wrote:

"After proving that heat can be generated by magnetic motors and the induction of magnetic forces can be increased or decreased at will, it is very interesting to explore whether there is a constant ratio between heat and the obtained or lost mechanical work.

For this purpose, only some previous experiments need to be repeated and simultaneously determined the mechanical force required to rotate the instrument.

According to the results of the thirteen groups of experiments, we can know that the heat that can warm up a pound of water by one degree is equal to the mechanical work of lifting a 3-pound weight by one foot.

Heat power equivalent!”

The magic network was shaking violently, and the power of the big source 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 can be converted with mechanical energy or other energy. During the transmission and conversion process, the total value of energy remains unchanged.

That is, when thermal energy and mechanical energy are transferred or converted, the total amount of energy must be conserved, which we can call the law of energy conversion and conservation.

In mathematics, we can express it in this way. When the system changes, assuming that the heat exchanged with the environment is Q and the work exchanged with the environment is, the change of the thermodynamic energy is

△U=Q+.”

Thomas just wrote that the power of the Dayuan had poured in like a tiger pounced on his food, and most of it poured into Thomas' body. He chose to improve his wizard qualification without hesitation. A large amount of source power made his wizard qualification reach the excellent level of natural overclocking almost instantly.

Betty and Donna also shared half of their source power. 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 former senior sister Blenia.

Betty's condition was very fluctuating. She flashed and disappeared, and appeared outside the gate of the central high tower Ace.

After reporting, Ace met Betty: "Your state has reached the critical point?"

Betty said without saying anything, "Yes, Lord Ace, I borrowed the Scepter of Heaven to assist in the breakthrough state, and I also need your dream seal."

Ace's demigod projection nodded, snapped his fingers, and a colorful dreamy flower appeared on Betty's shoulder.

"You go and borrow it from Witt. In addition, your recent series of research is better called thermodynamics? The law of energy conversion and conservation that Thomas just discovered is called the first law of thermodynamics!"

Betty had no objection to this and bowed happily and replied: "Thank you for giving the name."

Before she finished speaking, she had already flashed and disappeared. Ace looked at her petite back and disappeared, with a mysterious smile on the corner of her mouth, and returned to her desk.

Ace pushed away the imperial masterpiece that had just begun, and then unfolded another roll of magic paper to write down the beautiful bird-shaped letters.

"Since the first law of thermodynamics appears, will the second be far away? Will it be desperate?"

Ace couldn't help laughing. He decided to push and couldn't wait to see the expressions of other wizards.

Betty Wizard Tower, Betty, who had just borrowed the scepter of the Heavens, held the scepter. As the rotating day before yesterday, she could easily regain the scepter and blessed herself with the power of the entire heavenly realm.

Her epic wizard's body has long been semi-sacred, and her soul is in a state of about to be sacred but not sacred. At this moment, it is directly sacred, and the last bit of saving has been completed.

From the soul to the body, she realized true long-lasting vision. A little bit of spiritual light sprouts from the world of mind, and it was still a little short. She keenly felt that if this line was not available, her long-lasting state would quickly collapse.

This made Betty's mind even more, as if he had thought of something about thermodynamics.

Before she could catch the flash of inspiration, there was something more important at the moment. Betty instantly contacted the Dream Big Source and almost roared: "Dayuan, open up his person."

The news was instantly transmitted to Ace's projection through the fantasy source. He stopped his pen, opened his person immediately, and touched his nose: "The habitual closing of the person almost made Betty fail. It is indeed impossible to achieve anything without resources, but to a certain extent, the first law of thermodynamics can indeed explain the state of achieving a demigod."

As soon as Ace lay back, he slowly disappeared and appeared in the Betty Wizard Tower.

"I'll help you again, this is a drop of pure divine energy essence from the original body."

A light flashed in Ace's hand, and a divine essence containing terrifying and orderly energy floated to Betty and hanged above her head.

Betty is at a critical moment, and the essence of the divine power has made her accumulation more abundant. In the world of mind, Betty's mind has clearly seen the true spirit and is united with the true spirit. The entire world of mind has turned into chaos, and extremely hot flames are surging in her world of mind.

From the fire element to the phlogistin, from the phlogistin to the oxidation reaction, and then to the thermodynamics, the flame in Betty's heart has not changed.

"'Heat' is the core and drives 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, which must be a closed-loop system or an isolated system.

Demigod immortality is precisely because of the successful construction of an internal closed-loop system with great power. Of course, this system is not completely closed. It requires a switch to communicate with the "energy" of the outside world. However, as long as the core energy is maintained, the demigod can naturally immortalize.

If the half-plane is reflected from the world of mind, the closed-loop state will be condensed well and the conservation of one's own energy will be maintained. My mythological basic spell is the 'conservation ball'!"

In an instant, this empty world of mind and image absorbs high-quality energy from the outside world, forming a huge fireball in the entire world of mind and image. Then a strange mechanical structure sphere wrapped the huge fireball.

The mechanical structure made a creaking sound, and a large number of strange metals grew on their own, quickly completely wrapped the fireball. The texture of the metal actually made the world of mind gradually dark.

Betty opened her eyes, rushed into the sky, disappeared, and appeared outside the heavenly realm, in the wizard world.

The eyebrows suddenly turned bright red, like a soldering iron, which instantly expanded and turned into an extremely huge sphere. Betty twisted hard and separated his head from the sphere.
