second law of thermodynamics | JuE :'D's Profile

The next chapter is second law of thermodynamics. In this chapter i learn about heat engine,heat pum and refrigerator. Before this i don't know how refrigerator in my house work,now i know!! In addition, i also laern about Carnot cycle which is the best and perfect cycle as it is reversible cycle. However, this cycle only used as reference to know is it the system is possible or impossible. I also learn about entropy. Entropy generation increases in irreversible processes. If the entropy generation almost zero, thats mean the cycle is almost perfect.

The last topic is the power and refrigeration cycle. In this chapter i learn about Rankine cycle. Rankine cycle is the modification of the carnot cycle.
