Analysis:

This is because the ignition point of paper is generally 183℃, while the boiling point of water is only 100℃. When water is put into a smooth paper pot and heated until it boils, the water will continuously absorb heat during the boiling process, but the water temperature will remain unchanged, that is, as long as there is water in the pot, the water temperature will always be 100℃, which means it will not reach the "ignition point" of the paper, so the paper pot can be used to boil water and the paper will not burn out. Only when the water in the pot is burned out will the temperature of the pot be kept at normal temperature and pressure.

When the paper pot is heated, it will quickly transfer heat to the water in the pot. When water is heated to boiling. When water boils, the heat required for water evaporation and the heat generated by fire heating form a dynamic balance. Therefore, the water temperature will not continue to rise. The paper pot won't burn because it hasn't reached the ignition point yet.

The temperature rises from 1OO℃.
