Answer to Question #335355 in Molecular Physics | Thermodynamics for wig

Question

A Carnot engine has a power output of 139 kW. The engine operates between two reservoirs at 16◦C and 658◦C.

(A)How much thermal energy is absorbed each hour? Answer in units of J

(B)How much thermal energy is lost per hour? Answer in units of J.

Answer 1

$\frac{Q_2}{Q_1}=\frac{T_2}{T_1},$

$Q_1=448~J,$

$Q_3=Q_2-Q_2=309~J.$
