With reference to Figure 2. 1. 1, the thermally insulated cylinder, identified as B, contains carbon dioxide (CO2, MW1 = 44 Da, C! P, 1GI R = 3…

. 47, 1) retained by a friction-free mobile piston, which does not conduct heat and exerts, together with the atmosphere and a block arranged on its surface, a pressure equivalent to 1.5 bar. The cylinder identified as A, with a capacity of 1 m3, is externally covered with thermal insulation, includes a movable piston (negligible weight, friction-free and does not conduct heat) that separates cylinder A into two chambers. The lower chamber (A2) contains CO2 and is connected to cylinder B through valve 2 (V2). The upper chamber (A1) is coupled to a nitrogen line (N2, MW2 = 28 Da, C[mu]P, 2GI R = 7 2, 2) at 5 bar and 40 ° C through valve 1 (V1). In the initial state of equilibrium (1) valve 1 is closed and valve 2 is fully open. Additionally, the temperature of the N2 and CO2 in both cylinders is 20 ° C, and the volume of chamber A1 is 25% of the total of cylinder A. The process begins when valve 1 is opened allowing the N2 to enter the chamber very slowly. A1. The process stops (final state, 2) when the pressures of chamber A1 and the N2 line are balanced, instant in which valve 1 closes. Analyze the described system and / or process (s), specify the hypotheses with precision and / or simplifications that it considers relevant for solving the problem. Calculate / estimate for the final state (2) when the process stops. 2. 1. 1 Temperature (° C) of the N2 in the upper chamber A1. 2. 1. 2 Temperature (° C) of the CO2 in cylinder B. 2. 1. 3 Moles (mol) of N2 that entered the upper chamber A1. 2. 1. 4 Construct a schematic graph P (bar) versus V dm3 () that describes the volumetric behavior of N2 (2) in chamber A1 during the process. 2. 1. 5 Construct a schematic graph P (bar) versus V dm3 () that describes the volumetric behavior of CO2 (1) in both chambers during the process.
