Question:
Consider a well-insulated piston–cylinder assembly. O2, initially at 250 K and 1 bar, undergoes a reversible compression to 12.06 bar. You may assume oxygen is an ideal gas. Answer the following questions:
(a) What is the entropy change for this process?
(b) What is the fi nal temperature of the oxygen?
(c) What is the value of work for this process?
(d) If the oxygen in this system had undergone an irreversible compression to 12.06 bar, would the fi nal temperature be higher than or lower than that calculated in part (b)? Explain.
