    1.23 j/g. °C

    Explanation:

    Given dа ta:

    Mass of metal = 35.0 g

    Initial temperature = 21 °C

    Final temperature = 52°C

    Amount of heat absorbed = 320 cal (320 * 4.184 = 1338.88 j)

    Specific heat capacity of metal = ?

    Solution:

    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

    ΔT = 52°C - 21 °C

    ΔT = 31°C

    1338.88 j = 35 g * c * 31°C

    1338.88 j = 1085 g.°C * c

    1338.88 j/1085 g.°C = c

    1.23 j/g. °C = c
