The temperature in Hokkaido isn't low, right?The temperature in Hokkaido was relatively low. The annual average temperature was about 8.2 degrees Celsius, and the winter temperature was as low as-7.0 degrees Celsius. The lowest temperature would drop to-20 degrees Celsius or even lower. For example, the lowest temperature in some parts of Hokkaido had reached-41 degrees Celsius. However, the temperature varied from season to season. The average highest temperature in summer was 26.4 ° C. In general, Hokkaido was relatively cold compared to other parts of Japan such as Tokyo (annual average temperature of 15.4 ° C) and Japan (annual average temperature of 23.1 ° C).

Molar reaction energetics change with temperature, right?The standard mole of a chemical reaction changed with temperature. However, in engineering chemistry, it was generally believed that the change in the temperature did not change. Although most of the standard mole change in the table was at 298.15K, it could also be used for other temperatures (strictly speaking, the difference in the change in the temperature was different, but it was generally not greater than 5%, and this difference could be ignored). When Kirchhoff's formula was used to calculate the heat of reaction at different temperatures, if there was no phase change for each substance in the entire temperature range, it could be calculated directly. If some substances had a phase change, it could not be directly calculated using the definite integral or the uncertain integral. It needed to be calculated in sections.

What is the temperature of the high-temperature reactor?Different types of high-temperature reactors had different operating temperatures. For example, the product manufactured by Xi'an Taikang Technology had a working temperature below 400 ° C. There are also some reactors, such as the reaction kettle with jacket or coil heating. If water is used for heating and temperature control, the normal temperature water temperature machine can be used at 120 ° C, and the highest temperature of the high temperature water temperature machine is 180 ° C. If heat transfer oil is used for heating, the reaction temperature can be heated by external heat transfer oil when it is higher than 180 ° C, generally up to 250 ° C.

The Nine Heavenly Maiden chooses the right dayThe Nine Heavenly Maiden Day Selection Method was mainly used for marriage, business opening, moving, tourism, and other activities. The correct method was as follows:
First, he had to decide on the best date for the event, such as a wedding or opening.
Secondly, he carefully studied the Nine Heavenly Maiden's selection of good and bad days. This table was usually a large table, covering the solar and lunar dates of each month, the constellation, the prediction of the good and bad of each date, and the self-selection of the house. According to the changes in the heavenly stems and earthly branches, the good and bad of each day were predicted. It also covered the solar terms, winter and summer vacations, the lunar calendar, and other dates. Choose the appropriate date when you study the form and evaluate whether it is good or bad.
Finally, he would choose a suitable date according to his needs and arrange the corresponding activities. However, it should be noted that the reference table should be determined a few days before the event. Due to changes in astronomical data, the predicted results on the table may be different.
The temperature in DanzhouThe temperature in Danzhou changed at different times. According to the data in document 1 and document 2, the average high temperature in February was 26 ° C, the highest temperature was 36 ° C, the average low temperature was 16 ° C, and the lowest temperature was 9 ° C. It was also mentioned in document 2 that the annual average temperature of Danzhou City was 20 - 30°C, with the lowest temperature being 7° C and the highest temperature being 43° C. However, the specific temperature range of Danzhou City or the temperature data of other months were not provided. Therefore, it was impossible to accurately answer the temperature in Danzhou.
Boiling temperatureThe boiling temperature could exceed 65 ° C, which was considered the critical point for hot drinks and food to cause damage to the esophagus. In addition, the esophagus could only withstand temperatures of 50 ° C to 60 ° C. Hot drinks beyond this range may burn the esophagus, and long-term consumption may lead to cancer. However, the specific boiling temperature was not explicitly mentioned in the search results provided.
The temperature of fireworksThe surface temperature of fireworks is generally between 200 - 300 ° C, and the center temperature can reach between 700 - 800 ° C. The maximum temperature of unextinguished cigarette butts can reach 700 - 800 ° C. When cold fireworks are set off, the temperature at the spray mouth can reach 700 - 800 ° C.

The temperature in HokkaidoThe temperature in Hokkaido varies according to the region and season. As an important area of Hokkaido, Sporporo's annual average temperature was 5 ° C to 12 ° C, with an average of 12 ° C during the day and an average of 5 ° C at night. According to the data released by the Japan Meteorology Agency for the past 20 years until 2010, the average annual temperature in Sporo was 8.9 ° C, the average highest temperature in summer was 26.4 ° C, and the lowest temperature in winter was-7.0 ° C. However, the lowest temperature in Hokkaido during winter would drop to-20 ° C or even lower, with a record of-41 ° C.
