    Specific heat capacity of metal is 0.29 j/g.°C.

    Explanation:

    Specific heat capacity:

    It is the amount of heat required to raise the temperature of one gram of substance by one degree.

    Formula:

    Q = m. c. ΔT

    Q = amount of heat absorbed or released

    m = mass of given substance

    c = specific heat capacity of substance

    ΔT = change in temperature

    Given dа ta:

    Mass of metal = 1200 g

    Initial temperature = 10 °C

    Final temperature = 20 °C

    Heat absorbed = 3440 j

    Specific heat of metal = ?

    Solution:

    ΔT = 20 - 10 = 10 °C

    Q = m. c. ΔT

    c = Q / m.ΔT

    c = 3440 j / 1200 g*10 °C

    c = 3440 j / 12000 g.°C

    c = 0.29 j/g.°C
