Why can the paper pot boil water?What is the principle of it?
The paper pot can boil water is a physical phenomenon, the paper filled with water, so between the paper and the water will produce heat transfer, while the highest boiling water temperature was 100 degrees, but this has not reached the paper burns, that no matter how paper can reach 100 degrees. So the paper can boil water pot
Because water turns into a gas called vaporization from liquid, this process needs to be endothermic. Paper boil water, is to use this feature. In a standard atmospheric pressure, the boiling point of water is 100 degrees Celsius, while the paper burns at 183 degrees Celsius, while the water is heating, water constantly absorbs heat from the paper pot, even after the boil the temperature of the water is boiling, keep constant, so that the paper temperature will not exceed 183 degrees. So the boiling water pot does not burn the paper.
