1.95 mol of an ideal gas at 300 K and 3.00atm expands from 16 L to 28 L and a finalpressure of 1.20 atm in two steps:pyatigorskiy (fp3459) – Thermo HW – anderson – (22167) 2(1) the gas is cooled at constant volumeuntil its pressure has fallen to 1.20 atm, and(2) it is heated and allowed to expandagainst a constant pressure of 1.20 atm un-til its volume reaches 28 L.Which of the following is CORRECT?1. w = −4.57 kJ for the overall process2. w = 0 for (1) and w = −1.46 kJ for (2)3. w = −4.57 kJ for (1) and w = −1.46 kJfor (2)4. w = 0 for the overall process5. w = −6.03 kJ for the overall process
