Chapter 083 Electricity fails, the giant snake escapes

Following Zhou Wenwen's roar of forgiveness, the thunder directly penetrated Chen Zhi.

It directly evaporated Chen Zhi physically and crushed Chen Zhi microscopically, causing Chen Zhi to completely die and never be resurrected.

The giant snake that was fighting with the Knight of the Sky suddenly enlarged its eyes when it saw this scene. After a second passed, the giant snake didn't say a word and used its magical power to cover itself with the water in the pool and flew away into the distance.

Zhou Wenwen turned his head and was stunned for a second before he realized what was happening. He immediately activated the Bagua Shield with his fingers and released another thunderbolt in the direction of the giant snake's escape.

Perhaps because of the continuous launch, the energy and power of the thunder fired this time were lower than the last time. Zhou Wenwen, who saw this scene, didn't care at first, until he saw that the thunder completely avoided the giant monster. snake---

I saw a thunderbolt composed of dozens of thick-armed thunderbolts, completely parallel to the giant snake at a slow speed.

"This is... insulating pure water?!"

Zhou Wenwen, who came from the 21st century, naturally knew how this scene happened, but he was surprised that this situation could "happen naturally".

We who have studied physics and chemistry all know that water conducts electricity, but if water does not contain any substances, including minerals, then it is theoretically insulating.

But this cannot happen in reality, because water cannot be pure.

Pure water is an inorganic compound with the chemical formula H2O. It is a liquid with a certain structure. Although it is not rigid, its arrangement of molecules is much more regular than that of gaseous water molecules.

In liquid water, water molecules do not exist as single molecules. Instead, there are several molecules associated with hydrogen bonds to form water molecule clusters (H2O). Therefore, the orientation and movement of water molecules will be significantly affected by other surrounding water molecules. Influence.

There is no definite structural model for the structure of water. There are three main types that are accepted by most: mixed type, interstitial type and continuous structure (or uniform structure) model.

And you need to know that the reason why water conducts electricity is that there are free electrons in these substances.

Because of the directional movement caused by the action of electric current, the current generated during the directional movement is why metal elements conduct electricity.

Because most metals are composed of metal ions, these metal ions are mobile, but people know that the chemical symbol of water is actually a molecule.

Therefore, there are no free particles in normal water, but in ordinary water, impurities exist due to various substances, so these ions with freely moving ions can form an electric current.

However, in distilled water, only water molecules are weak electrolytes, and their ability to conduct electricity is very poor. Therefore, there is no way to form a stable free movement after electrification in distilled water.

Naturally, there is no way to conduct electricity, so it is difficult for distilled water to conduct electricity.

Pure water refers to H2O without impurities.

From an academic point of view, pure water, also known as high-purity water, refers to water with extremely high chemical purity. It is mainly used in biology, chemistry, metallurgy, aerospace, electricity and other fields. However, its requirements for water purity are quite high, so it is generally used in the most The most common one is the electronics industry.

For example, pure water used in power systems is required to have a low content of impurities reaching the "microgram/liter" level.

At the beginning of the 20th century, the German physical chemist W. Nernst came to the conclusion from studying the properties of chemical reactions at low temperatures: the entropy of the condensed system changes in the reversible isothermal process, and it will tend to zero as the absolute temperature approaches zero, which is called is Nernst’s theorem.

According to Nernst's theorem, the entropy of a condensed system will tend to a constant value S0 as the thermodynamic temperature approaches zero.

In order to determine this entropy constant, M. Planck proposed a hypothesis S1911=0 in 0.

The value of entropy thus determined is called absolute entropy.

Since the heat capacity is positive definite, the absolute entropy of the system S≥0. Planck's hypothesis can find a reasonable explanation from modern quantum theory: a system that reaches equilibrium at absolute zero is in a state of minimum energy.

This is a highly ordered state, and the corresponding thermodynamic probability W=1, so applying the Boltzmann entropy formula can get S0=0.

In 1912, Nernst derived a conclusion from Nernst's theorem: It is impossible to cool an object to absolute zero through a limited number of procedures.

This is the famous absolute zero inaccessibility principle.

Thermodynamics of irreversible processes is a branch of macroscopic physics. Also called non-equilibrium thermodynamics.

Specializes in the study of thermodynamic systems in a non-equilibrium state, the nature of the irreversible process that occurs when it approaches equilibrium, and the basic laws that its evolution must follow.

Irreversible processes usually occur in open systems, where both energy and matter are exchanged between the outside world and the system.

The macroscopic thermodynamic quantities that describe the state of the system are functions of space and time, and when a steady state is reached, they are only related to space.

However, the evolution of the process is always accompanied by an increase in the entropy of the system. Research shows that for non-equilibrium systems that are not far from equilibrium, the role played by the stable state is just like the equilibrium state in an isolated system.

Because the latter has the largest entropy, while the former has the smallest entropy increase rate.

The value of entropy increase per unit volume per unit time is called the entropy increase rate of the system.

In the production of pure water, various indicators stipulated in water quality standards should be determined according to the production process of electronic (microelectronics) components (or materials) (for example, it is generally believed that the size of particulate matter that causes damage to circuit performance is its line width. 1/5-1/10).

However, due to the complexity of microelectronics technology and the many factors that affect product quality, there is still no complete water quality standard suitable for certain circuit production based on process testing.

With the continuous revision of electronic grade water standards, many breakthroughs and developments in the field of high-purity water analysis, the continuous application of new instruments and new analysis methods have created conditions for the development of pure water production processes.

Since the lightning could not hit him, Zhou Wenwen had no choice but to give up the pursuit, canceled the spell casting, and allowed the giant snake to escape into the ruins of the building and turned to stare at the pool.

That's right, the reason why Zhou Wenwen gave up the pursuit was because he sensed something in the pool, which Zhou Wenwen couldn't find before through a pile of water.

Thanks to the giant snake, the water in the entire pool was sucked away, and what was hidden in the pool was revealed, a portal half a meter long and two meters high with a shining blue curtain.

It was also at this time that Zhou Wenwen understood why the water in the pool was so deep. The reason was that the water came from the portal, and obviously the other side of the portal was in the sea or a lake, or underground.

After deducing this result from the existing conditions, Zhou Wenwen felt a little relieved, but also a little uneasy. It always felt bad to have a portal leading to an unknown place here.

Zhou Wenwen waved and called, "Tisi, the Palace of Doom!"
