    Thermal capacity of 40 g of aluminium (specific heat, \[s=0.2\,cal/g\,\,K\]) is

    A) \[168\,joule/{}^\circ C\]

    B)        \[672\,joule/{}^\circ C\]

    C) \[840\,joule/{}^\circ C\]

    D)         \[33.6\,joule/{}^\circ C\]

    Correct Answer: D

    Solution :

    [d] Thermal capacity \[=ms=40\times 0.2=8\,cal/{}^\circ C\] \[=4.2\times 8=33.6joules/{}^\circ C\]
