5. A gas undergoes two processes: 1-2: polytropic compression from P₁ to P₂ with a polytropic exponent n and a compression ratio of r = 1 V2 2-3: Constant pressure expansion at P3 = P₂ until V3 = V₁. a) Sketch the processes on a single P-V diagram b) Determine the ratio of compression-to-expansion work as a function of n and r. c) Determine the value of letter (b) if n=1.4 and r=6.
