Vedclass · Answer

(C) The correct option is $C$.The thermal resistance of a thin layer of paper is very low. When the cup is placed over a flame,the heat is transferred through the paper to the water inside.Since water has a high specific heat capacity,it absorbs the heat effectively. As long as there is water in the cup,the temperature of the paper does not rise significantly above the temperature of the water (which is $100^{\circ} C$ at boiling point).Because the temperature of the paper remains below its ignition (burning) temperature,the paper cup does not catch fire.
