Answer:
[tex]Q=-526.6J[/tex]
Explanation:
Hello,
In this case, for the computation of the energy loss when the cooling process is carried out, we use the shown below equation:
[tex]Q=mCp\Delta T[/tex]
Whereas we need the mass, specific heat and change in temperature of iron within the process. Thus, the only value we need is the specific heat that is 0.444 J/(g°C), therefore, we compute the heat loss:
[tex]Q=26.4g*0.444\frac{J}{g\°C}*(26.0\°C-74.0\°C)\\ \\Q=-526.6J[/tex]
Negative sign points out the loss due to the cooling.
Regards.
