Question: A heat engine operates between a hot reservoir at temperature TH and a cold reservoir at TC = 3 0 0 K . In each

A heat engine operates between a hot reservoir at temperature TH and a cold reservoir at TC
=300 K. In each cycle, the engine takes in 2000 J of heat from the hot reservoir and expels 800 J
of heat to the cold reservoir. What is the minimum possible hot temperature TH for which this
heat engine can operate?
A.400 K
B.500 K
C.750 K
D.900 K
E. There is no such temperature.
