    Answer:

    \Delta T=57.01^{\circ} C

    Explanation:

    Given that,

    The mass of nickel, m = 70 g

    Energy absorbed, Q = 1756 J

    The specific heat of Nickel, c = 0.440 J/g °C

    We know that,

    The heat absorbed is given by :

    Q=mc\Delta T\\\\\Delta T=\dfrac{Q}{mc}\\\\\Delta T=\dfrac{1756}{70\times 0.44}\\\\=57.01^{\circ} C

    So, the change in temperature is equal to 57.01^{\circ} C.
