Chapter 7, Problem 7177

(choose chapter or problem)

A pistoncylinder device initially contains 15 ft3 of helium gas at 25 psia and 708F. Helium is now compressed in a polytropic process (PVn 5 constant) to 70 psia and 3008F. Determine (a) the entropy change of helium, (b) the entropy change of the surroundings, and (c) whether this process is reversible, irreversible, or impossible. Assume the surroundings are at 708F.
