A piston–cylinder device contains helium gas initially at
Chapter 4, Problem 118P(choose chapter or problem)
A piston-cylinder device contains helium gas initially at \(100 \mathrm{kPa}, 10^{\circ} \mathrm{C}\), and \(0.2 \mathrm{~m}^{3}\). The helium is now compressed in a polytropic process \(\left(P V^{n}=\right.\) constant) to \(700 \mathrm{kPa}\) and \(290^{\circ} \mathrm{C}\). Determine the heat loss or gain during this process.
