    Which of the given graphs proves Newton's law of cooling? 

    A)

    B)

    C)

    D) None of these

    Correct Answer: B

    Solution :

    [b] When hot water temperature (T) and surrounding temparature \[({{T}_{0}})\] readings are noted, and log \[(r  {{T}_{0}})\] is plotted versus time, we get a straight line having a negative slope; as a proof of Newton's law of cooling.
