Question

The entropy of the surroundings decreases by 8 J/K. The process is: Reversible: Irreversible: Impossible. An inventor claims to have constructed a heat engine that operates between 300 K and 1000 K with an efficiency of 40 %. This heat engine violates: The first law of thermodynamics: The second law of thermodynamics: C. The third law of thermodynamics. None of the laws of thermodynamics. After some tinkering the inventor claims to have increased the efficiency of the engine to 50 %. This new and improved engine: Is impossible. Is possible, but every stop must be reversible; Is possible, but every step must boo irreversible: Is possible and the steps could be reversible or irreversible. A temperature of absolute zero: Has already been attained: Can be attained and research is underway to do so; C. Cannot be attained. Southern California and Baja California often experience Santa Ana winds. In the Fall they bring very hot weather to the region, associated with forest fires. The winds are created when air descends across the mountains and is rapidly compressed, leading to an increase in temperature. The process is...

Explanation / Answer

32) d) Efficiency = 1-(TL/TH) = 1-(300/1000) = 70%

33) d) option is correct

34) c) cannot be attained

35) b) isobaric
