1. The problem statement, all variables and given/known data Consider a Carnot engine that operates between a hot reservoir at 63°C and a cold reservoir at -14°C. In running 25 minutes, this engine absorbs 590 J of heat from the hot reservoir. How much heat does it expel to the cold reservoir? 2. Relevant equations [tex]Q_H/Q_C = T_H/T_C[/tex] 3. The attempt at a solution [tex]T_H = 336k[/tex] [tex]T_C = 287k[/tex] [tex]Q_H/Q_C = T_H/T_C \longrightarrow 590/Q_C = 336/287[/tex] Solving for [tex]Q_C[/tex] I get 504 J, however, this is not the correct answer. What am I missing?
