What will happen to the water in the paper boat in the experiment of burning it? What about the paper boat?

I remember one week in the third class on Thursday afternoon. In science class, we did a little experiment. The experimental method is: put a paper boat made of white paper on a tripod, pour a certain amount of water into the paper boat, and finally gently move the alcohol lamp under the tripod. What about the water in the paper boat? What about the paper boat? The students are talking about it. The teacher said, "Listening is false, but seeing is true. Let's start the experiment. "

I saw the teacher put the tripod on the table, put the paper boat prepared in advance on the tripod, and then poured half the water from the beaker. In the last step, the teacher lit the alcohol lamp with a match torch. Now move the alcohol lamp under the tripod until the water and paper boat have changed. After a while, we found that the paper boat was not burned and the water in it was still there.

Our mouth is wide enough to put down an egg. The teacher said: "The reason why the paper boat was not burned is because the material needs a certain temperature when it burns, because the water is constantly evaporating while the paper boat heats up." The water evaporates and the steam takes away the heat, so the paper boat won't burn until the water is dry. "

I see: in the experiment of burning a paper boat, the water in the paper boat won't evaporate? Paper boats won't burn down.
