    The specific heat, c is 0.75 J/g°C

    Explanation:

    Heat or Energy, Q = 1500J

    Mass, m = 50g

    T1 = 0°C

    T2 = 40°C

    Specific Heat, c = ?

    We know,

    Q = mcΔT

    Q = mc (T2-T1)

    1500 = 50 X c X (40-0)

    1500 = 50 X c X 40

    c = 1500 / 2000

    c = 0.75 J/g°C

    Therefore, the specific heat, c is 0.75 J/g°C
