Why should heating be written as chemical heating question

Hehe! Could it be that the symbol only means heating?

The unit of prism is centimeter (cm m), and the unit name is prism diopter, which is symbolized"δ"Denote.

It can also represent triangles.

It can also represent non-ferrous metal deposits on the map.

It can also indicate altitude.

I've enumerated so much, I think you understand my intentions, right?

You don't let "it's a habit", I can only imply to you like this, I'm sorry! I'm a chemistry expert, but my language is mediocre, and I don't want to pick out too many words.

Do you choose to write Ignite, or δ

Why 1+1=2? Why did the U.S. military call D-Day D-Day? Customary or conventional.

Hehe, why bother so much? Then why do you say so many science symbols are written like that?

A consensus that provides convenience for everyone.

Internationally applicable!

The most essential difference between heating and high temperature is the difference in reaction temperature.

In the laboratory, alcohol lamps and water baths are generally used for heating, and alcohol blowtorches are used for high temperatures.

The high temperature is more than 1000 degrees Celsius, and it is generally high temperature in industry.

The heating is around 400 to 600, and the symbol for heating is .

High temperature generally refers to a temperature of more than 800 degrees Celsius, which cannot be reached by ordinary flames, and is generally provided with high temperature conditions with alcohol blowtorches in the laboratory. Generally, it is only used when it reacts with solids or with inert gases, and when solids decompose.

Heating generally refers to 800 degrees downward, the general flame can meet this requirement, in the laboratory generally use alcohol lamp to provide heating conditions. The heating conditions are generally used as conditions for the oxidation of inactive metals, and can also play some role similar to catalysts, and can also decompose solids. This condition is generally used for the reaction of metals and active gases.

I will tell you unequivocally, there is no problem with your writing, and the reaction of the heating temperature of the Gasen number is not higher than 800-1000 degrees, which can be expressed by triangles. Some reactions require high temperatures, such as firing calcium carbide, which is carried out in an electric arc furnace, and the temperature can reach 3000 degrees, so it is best to use high temperature to represent it, but it is not wrong to use a triangle to represent it, after all, high temperature is also the first to belong to the category of heating.

1) According to 1 minute, 0 5mol C generates 45kj, and the container dissipates heat, so the heater is used to provide heat 120kj-45kj 75kj per minute (2) the radius and height of the container are changed to 10 times that of the original buried, then the surface becomes 1000 times that of the original mountain search, and the average generation c per minute is 0 5 mol 1000 500 mol, the heat is released 45000kj, and the container dissipates 12000kj, so the cooler absorbs the amount of heat per minute 45000kj-12000kj 33000kj (3) unchanged.
