Hello. I'm having problems with one thermodynamics. I've used several equations but I'm still unable to get the right answer. A push in the right direction would be helpful. Thanks. Consider a process involving 1 mole of an ideal gas that takes place by the following pathway, at a constant temperature of 25oC: P1 = 3 atm → P2 = 0.75 atm → P3 = 3 atm Both steps occur irreversibly. work=?
