What is the altitude of Kunming? Is the boiling point of water 100 degrees?
The intersection of nanxi river and Red River is only 77 meters above sea level, and the average elevation in Yunnan Province is 2000 meters.
Kunming is located in the middle of Yunnan Province, with high terrain in the north and low terrain in the south. Most areas are between 1500-2800 meters above sea level.
The highest altitude is 4247 meters, the lowest altitude is 746 meters, and the average altitude is 1894 meters.
The temperature at which water boils is called the boiling point of water. We usually say "the boiling point of water is 100℃", which means that the boiling point of water is.
The temperature at which water boils at one atmospheric pressure (standard atmospheric pressure). So is the boiling point of water constant?
And then what? That's not true. The boiling point of water changes with the change of atmospheric pressure: with the increase of atmospheric pressure, the boiling point rises.
Tall man. On the contrary, if the air pressure decreases, the boiling point will also decrease. For example, the altitude of Kunming 1894 meters, the air is thin and angry.
The pressure is also low, and the boiling point of water in this place is reduced. In fact, the boiling point of boiling water is only about 93 degrees.
In the surrounding areas, the boiling point of water is different because of different altitudes.
