    Correct option is
    B
    Thermal capacity of the calorimeter is 4.5cal
    0
    /C
    C
    The heat required to raise the temperature of the calorimeter by 8
    0
    C will be 36 cal.
    (A) ms=4.5
    m⋅(0.09)=4.5
    m(
    100
    9

    )=
    10
    45

    m=50gm=0.5kg
    (B)water equivalent =
    S
    w

    ms

    Heat capacity=4.5×1=4.5cal/
    0
    C
    (C) Q=MSΔT
    =4.5×1×8
    =36cal
    Hence,
    option (B) and (C) are both correct answer.
