    A vessel contains 110 g of water. The heat capacity of the vessel is equal to 10 g of water. The initial temperature of water in vessel is 10°C. If 220 g of hot water at 70°C is poured in the vessel, the final temperature neglecting radiation loss, will be                                                                    [UPSEAT 2000]

    A)            70°C                                         

    B)            80°C

    C)            60°C                                         

    D)            50°C

    Correct Answer: D

    Solution :

               Let final temperature of water be q  Heat taken = Heat given 110 ´1 (q ? 10) + 10 (q ? 10) = 220 ´ 1 (70 ? q) Þ q = 48.8°C » 50°C.
