Using a gas sample of an ideal gas of .95 mol 3.00 atm and at 300 K expands from sixteen Litres to twenty eight Litres and a final pressure of 1.20 atm in two steps: in first step the gas is cooled at constant volume until its pressure has fallen to 1.20 atm, and in second step it is heated and allowed to expand against a constant pressure of 1.20 atm until its volume reaches twenty eight Litres. Now determine Which of the given data is correct?
(a). w = 0 for and w = -1.46 kJ for ,
(b). w = 0 for the overall process
(c). w = -4.57 kJ for (1) and w = -1.46 kJ for,
(d). w = -6.03 kJ for the overall process,
(e). w = -4.57 kJ for the overall process
