A Heat Engine Operates Between a Hot Reservoir at 1500

A heat engine operates between a hot reservoir at 1500 K and a cold reservoir at 500 K. During each cycle, 1.0 × 10⁵ J of heat is removed from the hot reservoir and 5.0 × 10⁴ J of work is performed.
-Determine the change in entropy of the cold reservoir.

A) -1.0 × 10² J/K
B) +1.0 × 10² J/K
C) -1.8 × 10² J/K
D) +1.8 × 10² J/K
E) -2.0 × 10² J/K
