1. 1 mole of an ideal gas expands adiabatically (Q1 = 0) from state A to state Calong Path I shown in the PV-diagram below with PA = 81 kPa, Pc = 1 kPa, VA = 1 L and Vc = 27 L. Path II takes the gas from state A to state B under a constant volume process. Path III is a constant pressure process that takes the gas from state B to state C. In other words, the gas can reach from state A to state C by either following Path I, or following Path II and Path III consecutively. Note: 1 kPa L = 1 J. P (kPa) c V (L) a.) Given 240 J of heat is released in Process II, find the number of active modes per molecule in the gas. b.) Write down the heat capacity in Process III and find the Work (Win) in Process III. c.) What is the area below Path I?
