  • question_answer
     A container contains hot water at \[{{100}^{o}}C\]. If in time \[{{T}_{1}}\] temperature falls to \[{{80}^{o}}C\] and in time \[{{T}_{2}}\] temperature falls to \[{{60}^{o}}C\] from \[{{80}^{o}}C\], then                                              [CPMT 1997]

    A)            \[{{T}_{1}}={{T}_{2}}\]     

    B)            \[{{T}_{1}}>{{T}_{2}}\]

    C)            \[{{T}_{1}}<{{T}_{2}}\]     

    D)            None

    Correct Answer: C

    Solution :

               Rate of loss of heat is directly proportional to the temperature difference between water and the surroundings.
