i would have done the integral of the equation using the values 15 and 5. then i would have used the equation Q=delta T x mass x the value i got from the integral
are these steps correct?

Q = m*intg(c*ΔT) = m*Intg[0.20 + 0.14

*T* + 0.023

*T*2]*dT.

Now find the integration between the limits 5 degrees to 15 degrees.
