murulidhara Posted July 24, 2007 Posted July 24, 2007 In one book I read about boiling water in a paper cup. Actually I tried heating a water in a paper cup till it becomes hot. Paper did not burn. I am interested to know the principle behind it. Similarly one more article in the book says If you roll a pencil with paper and heat it in a flame paper does not burn ( This I have not tried)
Bignose Posted July 24, 2007 Posted July 24, 2007 Well, paper burns at 451 degree Fahrenheit, and water boils at 212 degrees Fahrenheit.
