A heat engine whose thermal efficiency is 40 percent uses a hot reservoir at 700 K and a cold reservoir at 280 K. A) Calculate the entropy change of the two reservoirs when 1 kJ of heat is transferred from the hot reservoir to the engine. Does this engine satisfy the increase of entropy principle? B) If the thermal efficiency of the heat engine is increased to 70 percent, will the increase of entropy principle still be satisfied? C) Determine the maximum possible thermal efficiency of the heat engine for these reservoir conditions.
