A steel bar transfers energy from a thermal reservoir at (750 mathrm{~K}) to one at (520 mathrm{~K}).

Question:

A steel bar transfers energy from a thermal reservoir at \(750 \mathrm{~K}\) to one at \(520 \mathrm{~K}\). If the bar transfers \(1.5 \times 10^{6} \mathrm{~J}\) of energy during a certain time interval over which the temperature distribution of the bar does not change, what is the entropy change of the environment?
