SUMMARY
The discussion centers on the calculation of heat expelled by a Carnot heat engine operating between a hot reservoir at 63°C and a cold reservoir at -14°C. The engine absorbs 590 J of heat from the hot reservoir. The correct calculation for the heat expelled to the cold reservoir, using the Carnot equation Q_H/Q_C = T_H/T_C, reveals that the temperature of the cold reservoir must be accurately converted to Kelvin, resulting in Q_C being 504 J. The error arose from misreading the temperature due to formatting issues in the homework assignment.
