Engineering thermodynamic. Please all of this..I need the explanation.Please provide an explanation suitable with the marks ..Thankyou

Question 1 (6 Marks) Determine from the following data the type of process path going from state 1 to state 2, give your reason: (a) R = 1 bar, = 0.5 m3, R = 2 bar, k = 0.25 m3, Q+ 0 and W+0. (2 marks) (b)P = 1 bar, V = 0.5 m3, R = 2.64 bar, 12 = 0.25 m3, Q = 0 and W = -39.938 kJ. (2 marks) (C) R = 1 bar, n = 0.5 m3, R = 2.30 bar, k = 0.25 m3, Q+ 0 and W = +37.175 kJ. (2 marks) QUESTION 2 (6 Marks) What information do you need to (a) A system which is a fluid, undergoes a process. determine if there is a change of state? (2 marks) (b) A fluid system undergoes a process where Q = 0 and W = 0. Is there a change of state and why? (2 marks) (c) A water tank has an inlet and and outlet and the level remains constant in spite of flow entering and leaving. Explain why this is not a flow in equilibrium. (2 marks) QUESTION 3 (6 Marks) The following values of heat transfer and work at various points of a process were recorded in a factory: W = +9 kJ Q = +7 kJ W2 = -6 kJ Az = +5 kJ W3 = -8 kJ Oz = 0 kJ W4 = +12 kJ Q4 = -5 kJ What process was going on? Explain. (6 marks)
