2) Two kg of oxygen fills the cylinder of a piston-cylinder assembly. The initial volume and pressure are 2 m and 1 bar, respectively. Heat transfer to the oxygen occurs at constant pressure until the volume is doubled. Determine the heat transfer for the process, in kJ, assuming the specific heat ratio is constant, k= 1.35. Kinetic and potential energy effects can be ignored A.Q= 781.2 kJ B.Q871.2 kJ C.Q = 791.2 kJ D. Q = 771.2 kJ V3 = 2V, Pa l atm 2 kg V2m PI atm

I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)? https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857
I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass
Generate isometric drawing from multiviews using drawing tools or free - hand. Use approximate proportionate dimensions. Use plane sheet to draw or sketch isometric drawing.
I need these 3 parts answered TRUE or FALSE.
Choice the correct answer of the following statements: 1. The power transmitted of two pulleys connected by an open belt or crossed belt is a) directly proportional to their diameters; b) inversely proportional to their diameters; proportional to the square of their diameters; c) directly d) inversely proportional to the square of their diameters. 2. Two pulleys of diameters d1 and d2 and at distance x apart are connected by means of an open belt drive. The length of the belt is: a) π/2 (d: + d₂) 2x + (d: + dz)/4x; b) n/2 (d₁-dz) 2x + (di-dz)/4x; c) n/2 (d: +d₂) 2x + (di-d₂}/4x; d) π/2 (d₁-də) 2x + (d: +d₂)²/4x. 3. In a cone pulley, if the sum of radii of the pulleys on the driving and driven shafts is constant, then: a) open belt drive is recommended; b) cross belt drive is recommended; c) both open belt drive and cross belt drive are recommended; d) the drive is recommended depending upon the torque transmitted. 4. Due to not slip of the belt, the power transmitted of the belt drive:…
