    Q = mcΔT

    Where Q is heat or energy

    M is mass, c is heat capacitance and t is temperature

    You have to convert Celsius into kelvin in order to use this formula I believe

    Celsius + 273 = Kelvin

    21 + 273 = 294K

    363 + 273 = 636K

    Now ...

    Q = (0.003) (0.129) (636-294)

    Q = 0.132 J if you are using kilograms, in terms of grams which seems more appropriate the answer would be 132J of energy.
