Chapter 084 Adventure in the Unknown World

Zhou Wenwen beckoned and called, "Tis, the Palace of Doom!"

The next moment, Tis and the two doom knights appeared beside Zhou Wenwen through teleportation.

Needless to say Zhou Wenwen, Tis and the Doomsday Palace, who saw this scene with the help of the Doomsday Knight, instantly understood Zhou Wenwen's thoughts.

So Tis asked, "Do you want to go?"

"Well, I want to go over and check the situation. I can't let this thing be here."

Tis said, "Then I'll go too."

However, Zhou Wenwen shook his head and said, "No! The Doomsday Knight must send someone to follow me."

"why?"

Tis asked in confusion.

Zhou Wenwen had no choice but to explain, "The last time you crossed over will make you lose your strength. Now that the giant snake has not been killed, it is better to let you watch the house."

Tis had no choice but to promise Zhou Wenwen to stay at home. Before leaving, he gave Zhou Wenwen a set of armor.

An example of an irreversible process is only the process of free expansion into a vacuum.

That is, the initial gas initially occupies only a part of the container, and then fills the rest of the original vacuum).

That is, two objects with different temperatures reach thermal equilibrium through thermal contact.

But because of these processes, it cannot be restored to its original state without causing external influences.

So strictly speaking, the macroscopic processes that take place in a system where everything is composed of a large number of particles are irreversible.

Because in mechanical movement, there is always friction and loss.

In the process of heat transfer, heat is always transferred from the hotter part to the cooler part.

The total energy in these processes is still conserved and does not violate the first law of thermodynamics.

So, therefore, there must be other fundamental laws that will define the direction in which the actual process can proceed.

This is the second law of thermodynamics, and the entropy of the state function introduced on this basis.

The second law of thermodynamics is the law of thermodynamics that defines the direction in which the actual thermodynamic process occurs.

It confirms that the principle of entropy increase is established—there is a state function entropy in the thermodynamic system reaching the equilibrium state, the entropy of the isolated system does not decrease, and the entropy is the largest when reaching the equilibrium state.

That is to say, the second law of thermodynamics requires that the process that occurs in an isolated system proceeds in the direction of increasing entropy, which is called the entropy criterion.

Together with the first law of thermodynamics and the third law of thermodynamics, it forms the basis of the theory of thermodynamics.

Carnot's theorem derived from it points out the direction and limit of improving the economy of heat engine and refrigerator.

However, according to experience, it is pointed out that the thermal power conversion is irreversible, and the irreversibility of thermal power conversion can only be observed in a large number of heat engine cycles.

It is impossible to make a heat engine that only absorbs heat from a high temperature heat source without releasing heat to a low temperature heat source.

Therefore, after summarizing a lot of practice, it is concluded that it is impossible for us to absorb heat from a single heat source and turn it into useful work, so as not to produce other effects.

This is the Kelvin formulation of the second law of thermodynamics.

It negates the possibility of making perpetual motion machines of the second kind.

In addition to the irreversibility of thermal work conversion, heat transfer is also irreversible, heat is always spontaneously transferred from a high-temperature object to a low-temperature object, and the reverse process is impossible to proceed spontaneously.

On the basis of a large number of experiments, Clausius concluded another statement of the second law of thermodynamics - it is impossible to transfer heat from a low temperature object to a high temperature object without other effects.

The probability that a macrostate appears is related to the number of microstates it contains.

The number of microstates corresponding to a macrostate is called thermodynamic probability.

The greater the thermodynamic probability, the more chance this macroscopic state will be observed experimentally.

The equilibrium state is the macroscopic state with the largest thermodynamic probability W and has a definite value. Therefore, if the entropy of the equilibrium state is defined by the Boltzmann formula as S=klnW, the system will spontaneously transition from a state with a smaller probability to a state with a probability of The irreversible process of the larger state is a process of increasing entropy, which explains the principle of entropy increase in microscopic.

The third law of thermodynamics refers to the basic law that must be followed for the change of material properties when the limiting temperature tends to absolute zero.

It is summarized on the basis of a large number of experimental observations, and the main content is the Nernst theorem and the absolute zero unreachable principle derived from it.

Therefore, a plug-in shield was designed in the Palace of Doom, and the method of plug-in was used to solve the external flame caused by the Jewel Knight 0155 falling into the earth at high speed.

In February, Jewel Knight version 0155 was approved, allowing mass production, and the name was changed to Sky Knight, version 190.2, indicating that it was finalized in February 190 AD.

Since then, in addition to having three delivery bins or Flint Knights on the Guardian platform, there are 15 delivery bins and 36 delivery bins on Platform 2 newly built in April, all of which are Sky Knights.

Of course, after finishing the final design for the Knights of the Sky, the Temple of Doom also began to tinker and update the Knights of the Sky, but it was always just a small patch.

......

"Damn, what about the **** Han Sheng?"

The answer to Zhang Ji was the response from the rare imperial guards. Zhang Ji, who turned around and saw this scene, was suddenly saddened and extremely angry.

The great change in Zhang Ji's heart triggered the items in his arms, the temperature suddenly rose from 0 degrees and a green light bloomed.

Seeing the green color that suddenly appeared, Zhang Ji was taken aback and wanted to take out this item, but it was impossible for him to make this action during battle.

So Zhang Ji quickly withdrew from the battle, and then he had time to stretch his hand into his arms, took out the item whose temperature was rising rapidly, and threw it on the ground.

It was a palm-sized mirror five or six centimeters thick, but it was now torn apart.

In the next second, the temperature control system in the mirror triggers the signal transmitter and emits a signal. The transmission tower arranged on the Taihang Mountains, after receiving the transmitted signal~www.wuxiamtl.com~, immediately transmits the signal to the geostationary orbit. Communication satellite, the communication satellite is then transmitted to the guardian platform through the relay station.

When the guardian platform received the signal and located the location, the Dooms Hall determined that it needed to deliver 6 delivery bins according to the situation, so the people in Xiangling were fortunate to see such a scene:

I saw 6 big fireballs falling in an oblique line in the sky, falling to the Huns accurately, Boom!

The gas explosion was set off on the spot, and many Southern Huns were lifted into the air and fell to their death on the spot, but more importantly, the formation of the Southern Huns was chaotic and their morale collapsed.

Seeing this scene, Huang Zhong and Zhang Ji immediately realized that this was a good opportunity, and they each led the Imperial Forest Army to charge.

On May 13, Huang Zhong and Zhang Ji spent two days to capture more than 1,000 southern Huns who had escaped, and they were imprisoned in Xiangling and guarded by Zhang Ji.
