    Ideal gas compressed adiabatically, cooled isochorically, expanded isothermally

    Yeah, I tried answering with both the rounded and not rounded intermediate and I noticed the difference too, but it still returned both answers as incorrect. Usually when just the sign is wrong it'll say so as well... I've been going off of an example in my book that is pretty much the same...

    Ideal gas compressed adiabatically, cooled isochorically, expanded isothermally

    Homework Statement A 26-L sample of an ideal gas with (gamma)= 1.67 is at 250 K and 50 kPa . The gas is compressed adiabatically until its pressure triples, then cooled at constant volume back to 250 K, and finally allowed to expand isothermally to its original state. Homework...
