In this case, we relate the heat, mass, heat capacity and temperature when a thermal change is carried out as shown below:

Q=mCp(T_{final}-T_{initial})

Now, for the given data, we compute the absorbed heat (due to the temperature increase) as follows:

Q=15.0g*0.900\frac{J}{g^oC}*(350^oC-25^oC) \\\\Q=4.39x10^3J=4.39kJ

Best regards.
