Most types of paper burn at 233 degrees Celsius (or 451 degrees Fahrenheit). As water heats up, it draws heat away from the paper, preventing it from reaching that critical temperature. Heat also continues to escape through the vapor that is created when water boils.
How can water boil in paper without burning it?
The paper cup in which the water is placed has an ignition temperature higher than the boiling point of the water, making the water have a higher potential heat of evaporation. This also means that the temperature provided to the water may not exceed the boiling point. Thus, the water could boil in the paper cup without burning the cup.
What temperature does paper boil?
Paper ignites at temperatures much higher than the boiling point of water. Paper ignites at about 230 degrees Celsius; water boils at 100 degrees Celsius.
Can we boil water in a paper cup with paper catches fire easily?
The paper cup can boil water because the heat energy supplied to the paper cup is rapidly passed to the water. Thus, the paper ignition temperature is not achieved and therefore does not catch fire.
How do you boil water into paper?
