The document provides detailed notes on the Second Law of Thermodynamics, which states that entropy in an isolated system always increases over time. It explains that energy spontaneously spreads from regions of higher concentration to lower concentration, making processes irreversible. Key concepts include entropy, the direction of natural processes, and the inefficiency of energy conversions. Practical examples and applications in engines and refrigerators illustrate the law's significance in...

First assessment quiz on refrigeration systems. Topics includes: Reversed Carnot Cycle, Heat Engine, Heat Pump, and Refrigerating Machine. Usually taken at 2nd semester of 3rd year mechanical engineering students at Holy Angel University. I tried to make a clear and concise solution in a manner any student can easily follow the logic of the processes. Thanks
