Kaichi takes Jancy and Fessenden into the A Song of Iron and Fire restaurant.

Yang Xi looked at the familiar layout of the restaurant and asked with some curiosity: "Why did you open your restaurant wherever you went?"

"Because everyone needs to eat, just like my cook, if everyone can eat like her, the restaurant industry will be the number one profitable industry. ”

Speaking of his cook, Jia Yi looked a little helpless.

Yangxi's expression was also a little subtle: "Although your cook is petite, her appetite is indeed not small. And he ate so much that he didn't even grow taller. ”

Fresenden laughed on the side: "If you can grow tall just by eating, the halfling will not be so small, but your cook is also more edible among the halflings." ”

Jia Yiyi's face was helpless, Erica was not able to eat a little bit, he knew that halflings would eat several meals a day, but he never thought that halflings could eat so many things in one meal. At every meal, Erica eats almost the same food as an adult lunch, only less for morning tea and supper, which is said to be more "healthy".

He originally thought that the halflings ate more often, and the amount of food per meal would be smaller.

Eating too much is not counted, Erica's appetite is also poor, and she has to eat well, since Erica came, the cost of food in the Jia family has increased at least five times, generally speaking, the more people, the less the per capita cost is actually less.

It's no wonder that Erica put a lot of emphasis on eating and eating at the time.

Today when they came over for dinner, Jia Yi didn't dare to call Erica, not even Winnie, so as not to let Erica know.

Coming to the reserved box and sitting down, Jia Yi said to Yangxi: "Although the signature is the same, the dishes in the restaurant here are richer than those in the college. You can often buy all kinds of Warcraft meat here, and the handling of Warcraft meat here is also better. ”

Warcraft meat is not easy to handle, most of the Warcraft meat is very coarse, if it is not cooked properly or even bitten, the processing of Warcraft meat is also a top-notch cooking skill. However, as a place where mages gather, Moshacher is already very mature in the processing of Warcraft meat, basically no matter what kind of Warcraft meat it is, it is poisonous and non-toxic, delicious and unpalatable.

"There is still elf rice available here, so it's a rare opportunity to come and try it today, and to celebrate the development of the halogen lamp. ”

"Elf rice? Rice? No, it can't be pure elf rice, is it? This restaurant is so powerful? I heard that the Skoll Chamber of Commerce sells elf rice, but it's hard to buy, I haven't bought it a few times, and it's made into rice to sell here?"

Fresenden looked at Jia Yi in surprise, and his speech was a little incoherent. Most people are reluctant to take elf rice to cook and eat, and most of them are mixed with other grains or boiled porridge to eat, even Jiayi cooks porridge most of the time.

"Elf rice here can't be adulterated, is it?" or is it just called that?" Fresenden was still a little unconvinced.

"Don't worry, I'm one of the bosses here, the owner here is Selena, and the cooperation with the Skoll Chamber of Commerce is very stable, so it's not a problem to get some elf rice. ”

In fact, the Valoka Chamber of Commerce was also able to purchase some elf rice, but it was not sold publicly, and it was all digested internally.

The elf rice here is not available to everyone, and it is available in limited quantities and is specially designed to attract customers and enhance the restaurant's style. Even in Moshacher, this is the only one that can serve elf rice.

It's almost the same as the feeling of pickling 4 or 50 years of wild ginseng into dried radish, full of the feeling of being overwhelmed.

However, this also shows that the yield of elf rice is not small, and now the college has developed all the planned 100 hectares of land, harvested more than 10 tons of elf rice last year, and this year it is expected to have more than 15 tons. Although if you count the heads, a mage can't share much, not even a catty, but the amount is already a lot, at least the elf rice imported from Elf Island every year in the past is much less than this.

Elf rice with mapo tofu is a rare treat.

Jancy asked Fresenden: "Now that we have made halogen lamps, do we need to replace the current bulbs? ”

Halogen lamp is filled with halogen gas in the incandescent lamp, the tungsten filament of the incandescent lamp will be combined with the halogen after sublimation to generate tungsten halide compound, tungsten halide back to the center of the bulb, contact the hot tungsten filament, because the tungsten halide is very unstable, it will be re-decomposed into halogen vapor and tungsten when heated, and the tungsten will be deposited on the filament to make up for the evaporated part.

Before Jiayi crossed, the most common use of halogen lamps was the headlights of the car, although this was the most backward headlight in the car.

Halogen bulbs don't darken like regular high-end incandescent bulbs and last longer. The so-called halogen is the column of chlorine in the periodic table, because this column of elements and metals produces a large number of inorganic salts, which are called halogens. After the publication of Jiayi's periodic table, this column was also named the same way.

"We have already thought about this, and we have decided not to replace the existing street lights, and halogen lamps are not necessarily the best, everything will wait for the second phase," Fresenden said. ”

Jia Yi has always suggested to Fessenden: "You should increase the publicity of electricity, especially the safety of electricity, so that people do not touch the wires at will." Now they are all street lights, and the wire racks are out of the reach of people in the air, so you need to pay special attention when the lights enter the house in the future. And for the electric shock, you must have psychological expectations, this kind of thing will definitely happen in the future, don't give up the application of electricity because of pressure. ”

Fresenden nodded solemnly: "I will pay attention to this, and I will explain it to His Excellency Wilmot." ”

After the elf rice came up, several people were not interested in chatting at all.

Returning from the dinner, Kaichi plunged headlong into the lab, where he was now studying absolute zero.

Absolute zero is an extension of the second law of thermodynamics, which says that it is impossible to transfer heat from a cold object to a hot object without causing other changes. At this time, there needs to be a definition of temperature, the current temperature is to use the freezing point of water as the temperature scale, which is not accurate, people need a more accurate temperature, at this time, there is a thermodynamic temperature scale, and the lower limit of the absolute zero thermodynamic temperature.

At a constant pressure, for every 1°C increase in temperature, the increase in the volume (expansion rate) of a certain amount of gas is a fixed value, and the volume expansion is linearly related to the temperature. When the volume of the gas shrinks to 0, the temperature will drop to the lowest point, and the result is absolute zero. In the case of molecular motion theory, it is absolute zero when a molecule stops moving.

Jiayi extrapolated the absolute zero degree backwards according to the volume of the gas, calculated the linear relationship between the volume expansion and the temperature as 1/273, and finally determined that the accurate value of these coefficients was 1/276.15 after many calculations. The absolute zero is -276.15 degrees.

This value does not correspond to the previous life, the temperature is lower, but this is not the absolute zero here, but the freezing point. The freezing point of water decreases with the increase of air pressure, and it can be known by definition that absolute zero is constant in any world, which means that the air pressure in the two worlds is different, the air pressure in this world is slightly lower, and the freezing point is higher than that of the earth, so it seems that absolute zero is lower.

Absolute zero is only a theoretical value, because it is impossible to achieve either a reduction in the volume of a gas to zero, or a complete cessation of the motion of molecules. When molecules stop moving, not only matter, but even time freezes, and absolute zero can freeze everything, including time.

As Kaichi calculated absolute zero, he also summarized the second law of thermodynamics.

There are many ways to express the second law of thermodynamics, such as why the second type of perpetual motion machine is impossible to realize, and there is also a statement called that the entropy of an isolated system never automatically decreases, and the entropy does not change in the reversible process and increases in the irreversible process, which is referred to as the entropy increase theorem.

However, at this time, Kaichi had not yet introduced the concept of entropy, so he did not propose the entropy increase theorem at this time.

Otherwise, the Doomsday Cult would have liked the entropy increase theorem.
