There were three kinds of qi in a family. Human qi and firework qi were two of the most important kinds of qi. Popularity referred to the number of people in the family. The more people there were, the better, because a strong popularity could bring prosperity and good luck to the family. Smoke and fire referred to cooking at home instead of eating out or ordering takeout. The existence of this kind of smoke could increase the warmth and vitality of the family, and also contribute to the family's blessing and good luck. As for what the third type of qi was, the search results provided no clear information.

Liquefied natural gas was the product of natural gas purification and liquefied treatment. The main component of natural gas was methane, and there were also a small amount of ethane, propan, butane, and nitrogen. Among them, methane accounted for more than 80%. It was evolved from the remains of ancient creatures under high temperature and high pressure conditions after hundreds of millions of years. It was extracted from oil and gas fields and coal bed gas, and was generally transmitted through pipes. Its heat value was about 8000 - 8500 kcal/m3. It was colorless, odorless, and non-toxic, but too high a concentration would cause suffocation. For safety reasons, pungent odor substances such as thiols will be added. It is a clean and environmental friendly high-quality energy source. The carbon dioxide produced by combustion is lower than other fossil fuel, and the greenhouse effect is small. Gas was a mixed gas formed by coal or coke, which had been dry distilled or vaporized under high temperature and absolute oxygen conditions. The main components were carbon dioxide and hydrogen. It was widely available, easy to operate and use, and economical. However, carbon dioxide was easy to combine with the human body's hemoglobin-causing oxygen deficiency. Its safety was relatively low. Its heat value was about 3500 kcal/m3, and it was generally transmitted through pipes. The novel "Watching the Moon on Fish Island" is equally exciting.

Gasification was the process of turning gas into liquid (condensation). It involved a series of thermal processes. The purpose was to cool the gaseous working medium to the required low temperature and compensate for the cold loss of the system to obtain liquefied gas. This process usually required multiple compression and expansion steps, and sometimes a turbine expansion machine was used. In the liquification cycle, the gaseous low-temperature working medium not only acts as a cryogen, but it is also liquefied, and part or all of it is output from the cryogenics as a liquid product. These liquid products can be used in processes that require low temperatures, such as coolants in low temperature experiments, or in gas separation processes, such as the separation of liquid air into oxygen, nitrogen, and so on. Different liquids had different application scenarios. For example, nitrogen was the earliest used cryogen. Although it had been replaced by other cryogenics in residential and commercial applications, it was still commonly used in industrial freezing. In the medical field, liquid oxygen was used to provide oxygen to patients with respiratory problems, and liquid nitrogen was used in low-temperature surgery, such as semen freezing. Liquid chloridewas used for water treatment, including water purification, industrial waste disposal, sewage and swimming pool purification, as well as paper pulp and textile bleaching. It was also used to produce carbon dioxide, diols, and other organic compounds. In addition, liquefied gasoline can be used for storage, cooling, and air conditioning systems; helium is liquefied through the Linde-Thompson cycle for pre-cooling process. The boiling point of liquid helium under normal atmospheric pressure is 4.22K.(-268.93 °C). When the temperature is lower than 2.17K, the liquid 4He will become a superfluid with zero viscous and other special properties. Air can be liquefied by the Linde process or Claude process. Through these processes, nitrogen, oxygen, Argon, and other rare gases can be separated from the air. From the perspective of the gas industry, there was also the concept of low-pressure liquefied gas. Gas with a critical temperature greater than 70 ° C was called low-pressure liquefied gas.

Cartoon gas is often a fictional concept and doesn't exist in reality. Traditional gas is what we commonly use for various purposes like heating and fuel.

There were two main ways to liquify gases: one was to lower the temperature. As long as scientific conditions allowed, any gas could be liquefied when the temperature dropped sufficiently. The second was to compress the volume. Some gases could be liquefied by compressing the volume at room temperature. However, gases such as hydrogen and nitrogen had very low critical points. They had to be deeply cooled to be liquefied while being compressed. The novel " Watching the Moon on Fish Island " is equally exciting. Everyone is welcome to click and read it!
