The cubic equation of state gives three roots for volume at the saturated state. At the critical point the roots are a. Imaginary and distinct b. real and repeated c. real and distinct

Please show all work for Exercise 2 please!

What is the effect of overdamped state?

2. An ideal gas (the weight is m kg) in an idealized piston-cylinder assembly undergoes a series of processes from state 1 to states 2, 3 and 4. Each state is at equilibrium. The gas can be modeled as a closed system. Ignore changes of KE and PE. The states are fixed by the following properties in the table: State 1 2 3 4 8 7 9 Note: State 1 to 2 is a constant-temperature process. State 2-3 is a constant-volume process. State 3-4 is a constant-temperature process. (a) Mark the states 1-4 and draw the three processes (1-2, 2-3, 3-4) on the following p-v diagram. p (bar) 4 5 3 1 2 0 p (bar) 1 3 1 6 3 v (m³/kg) 3 1 1 2 2 300K 600K T (K) 300 300 600 600 3 4 5 v (m³/kg) 6 7 8 (b) Use equations and simple texts to explain and answer the questions for the two processes (process 1-2, and process 2-3), respectively. (i) How does the internal energy change during each process: no change, increase or decrease (AU)? (ii) How does the enthalpy change during each process (AH)? (iii) Is the work…
