water has the largest amount of speci. Heat. So that, when a water-filled paper cup held in a flame, most of the amount of heat spend to increase the temperature of the water in it. So that the paper cup can't get the proper heat for burning. {till the water boiled & finished for a large amount}

Paper burns at 451 degrees Fahrenheit. The water in the cup cannot get above 212 degrees, the boiling point of water, until the water is gone. It is possible for the cup to burn down to the water line, of course.

∙ 12y agothe paper cup cannot become appreciably hotter than the water it contains
Wiki User
∙ 13y agoIt prevents the paper from getting hotter than the boiling temperature of the water.
Paper will burn at 451°F. Water boils at 100 Celsius.
Wiki User
∙ 12y agoThe heat caused by the fire gets conducted to water, so the ignition temperature of the plastic bag is not reached.

Why does a paper cup not catch fire when filled with water?
