Answer:


\Delta T=18.24\°C

Step-by-step explanation:

Hello,

In this case, since the equation for computing the heat in terms of mass, specific heat and temperature change is:


Q=mCp\Delta T

For the given heat and mass, and considering the specific heat of iron to be 0.444 kJ/(kg°C), the resulting temperature change is:


\Delta T=(Q)/(mCp)=(97.2kJ)/(12.0kg*0.444(kJ)/(kg\°C))\\ \\\Delta T=18.24\°C

Best regards.
