Question

Ideal Gas Process Problem natomic ideal gas is run through the cycle shown starting in state A. The temperature of the gas in state A 300 K. The cycle happens within a sealed chamber outfitted with a piston as necessary. P (Pa) A 5.00 x 105 + The Herring Cycle 1.00 x 105 + 14300k 2.00 6.00 The cycle is composed of three processes, A B, B C, and C - A. 1) For each individual process... (a) (b) Name (if possible) the process by type, and enter this name in Table 2. Name (if po Compute the initial and final value of each of its thermodynamic state variables, P, V, n, T, and U, and enter them in Table 1. Compute the work W done by the gas, and enter it in Table 2. Compute the change in internal energy AU of the gas, and enter it in Table 2. Use the First Law of Thermodynamics to compute the amount of heat transferred Q, and enter it in Table 2. Is the heat absorbed or emitted by the system?

Answer 1

A to B volume is AB process is constant Iso-choric B to C P = -4V + 7x100 process is Isotropic cto A .: C-A pressure is constant process is Isobaric ® at "Å P = 1x105 Pa nA = PAVA VA = 2 m3 RJA na=zxros 8.314 x 300 ТА = 3ook na=80.2 At'3" PB = 5xros pa VB = 2m3 2xsoros 80.2% 8314 - PBVB = 80.248 nx8314 TB = isook , "g= 80.2 PC Vc At "Ć" ñR Pce ixro pa гох Б 80-288314 T = Te= 400k Vc =6 at = 8oz Шар О L' Bc =(2x4x4X10%) + xoxu WBC = 12x1055 WICAS - 1xcos x 4 = -4X10J AUAB = nCudt Le0-2x3x8394 x 1200 2 Ause = 12x05 J 2 2 AUBC = naudt = 802*38° 314x Coo DUBC = 6 x605J Duca - nardī&02x35&3M48–600 DUCA = -6x60SJ @ dama duast d was = 12 x10J da bc = duzct dWBC = 18x1055 da ca a duca td wca = -loxross ☺ @ Quer = 20x1055 Oci) Q H = do + de 230 x105 - Cis q = 1oxioso Cris a = zoxross © Wo = 20X10SJ + AB BC 00 eticum, и = 1 хоо Licil = 66-7%
