Question

Answer the following by appropriately matching the lists based on the information given in the paragraph. In List-I, certain situations are depicted where steam at 10 0 ∘ C is used to melt ice at 0 ∘ C by means of a conducting body which is insulated to prevent heat losses to surrounding. Match the numerical value of question asked in each entry to the corresponding entry in List-II. Symbols have usual meaning.
