Assuming the ideal gas model determine a) The entropy change, in Joules/K. QUESTION 9 10 points b) The pressure at the final state (bar). TTTT Paragraph Arial 320 %DOQEEZETT. E.E. BE

Answer 1

Given data? Initial volume V = 103 m3 P = 3.4 bar = 340kPa Ti = 246.85°C = 519.85% Pulog = constant (tere n=1.8) final state. Temperatcere Tz = 36.85€ = 309.85% Gas Carbon Monoxide (Co).
