A cylinder-piston sistem contains CO2. The sistem experiments an initial expansion where P1 = 20 lbf / in2 and V1 = 0.50 ft3 till the final state where P2= 5 lbf / in2 and V2= 2.50 ft3. The relation between pressure and volumen during the process is P = A + BV, where A and B are constants. a) For the CO2, evaluate the work done on ft / lbf and Btu b) Calculate the values of A and B...

TB4 The quasi-static ideal gas cycle shown to the right has three legs, an adiabatic leg #1 from (PyVị) to (P-1 atm, V3), followed by an isobaric compression leg #2 from (P-1 atm, V3) to (P -1 atm,Vi), and ending with a constant volume pressurization leg #3 from (P-1 atm, VI) back to the initial state to complete the cycle. There are n moles of gas. What happens to the internal energy ( Ein) during leg #2 of this process?...

When the pressure P is constant at 1 atm, the melting point of Br_2 is T_m = 265.95 K and its boiling point is T_b = 331.85 K. Br_2 is therefore liquid at 298 K and 1 atm but it also has a finite vapor pressure hence the property of both liquid and gas Br_2 can be obtained at at 298 K and 1 atm. Using a DeHoff equation and the thermodynamic table on D2L calculate the absolute molar entropy...
