Carnot Cycle We examine a Carnot Cycle engine. Next time you'll learn about the fridge version. Hot reservoir at Th Hot reservoir at Th Engine: Qh Qc Wby Fridge: Qh Qc Won Cold reservoir at Tc Cold reservoir at Tc First consider a Carnot engine that operates between a hot reservoir at 58°C and a cold reservoir at -16°C. In running 25 minutes, this engine absorbs 600 J of heat from the hot reservoir. 1) How much heat does it expel to the cold reservoir? Qc = 2) How much work does it do in this amount of time? Wby = 3) What is the upper limit on the efficiency of any heat engine operating between these two reservoirs? ?max =
