    Answer:

    c=0.133\ J/g^{\circ}C

    Explanation:

    Given that,

    Heat required, Q = 512 J

    Mass of the substance, m = 255 g

    The change in temperature, \Delta T=15^{\circ} C

    Let c be the specific heat of the substance. We know that the heat required to raise the temperature is given by :

    Q=mc\Delta T

    Where

    c is the specific heat of a substance

    So,

    c=\dfrac{Q}{m\Delta T}\\\\=\dfrac{512}{255\times 15}\\\\c=0.133\ J/g^{\circ}C

    So, the specific heat of the substance is equal to 0.133\ J/g^{\circ}C.
