QUESTION 26
In an experiment, a rigid container holds 3 kg of refrigerant-134a initially at 30°C and 180 kPa. The refrigerant is now cooled while being stirred until its pressure drops to 80 kPa.
At the initial state, the specific entropy is
(to 4 d.p.) in
(insert unit symbol), specific volume is
(to
5 d.p.) in
(insert unit symbol),
At the final state, the specific volume is
(to 5 d.p.)(insert space then init symbol), the quality is
(to 3 d.p.), the specific entropy is
(to 3 d.p.)(insert space then init symbol)
The entropy change of the refrigerant during this process is
(to 3 d.p.)(insert space then init symbol).
(yes/no).
From the final answer, does the systen violates the second law of thermodynamics?
NB: m may be written as m3.
