An ideal gas described by Ti = 300 K, Pi = 2.00 bar, and Vi = 15.0 L is heated at constant volume until P2 = 20.0 bar. It then undergoes a reversible isothermal expansion until P3 = 2.00 bar. It is then restored to its original state by the extraction of heat at constant pressure. Depict this closed-cycle process in a P-V diagram. Calculate number of moles n ( two decimals, as 3.21) = [n]; V2 (unit L, no...

One mol of an ideal gas described by Ti = 300 K, Vi = 2.46 L, and Pi = 10 atm undergoes isobraic expansion (constant pressure) until V = 5 L. Next, it undergoes a reversble isothermal (constant temperature) expansion until P = 1.00 atm followed by isobaric compression to T = 300 K. Finally, it is restored to its original state by reversible, isothermal compression. a) Depict this cyclic process on a P-V diagram. b) Calculate w, q, deltaU,...
