    Answer:

    1.18010256J/Kg°C

    Explanation:

    The quantity of heat energy is expressed as:

    Q = mct

    c is the specific heat capacity

    t is change in temperature

    Q = 4.184×2.2

    Q = 9.2048Joules

    m = 150g = 0.15kg

    t = 52°C

    Substitute and get c

    9.2048 = 0.15c(52)

    9.2048 = 7.8c

    c = 9.2048/7.8

    c = 1.18010256

    Hence the specific heat capacity of the dish is 1.18010256J/Kg°C
