ELEN [110]

Answer:

$Q=93.3kJ$

Explanation:

Hello,

In this case, by knowing that the heat due to a change of temperature is given by:

$Q=mCp\Delta T$

Whereas Q accounts for the heat, m for the mass, Cp the heat capacity and ΔT for the change in temperature. In such a way the required heat results:

$Q=24.7kg*236\frac{J}{kg^oC}*(30.0-14.0)^oC*\frac{1kJ}{1000J} \\Q=93.3kJ$

Best regards.
