    How can I calculate final pressures in a reversible argon expansion?

    nevermind i got it all -- I just didnt have my P and V in the right units... anyway i found V1 using the ideal gas law, and the used boyle's law to find P2. Seems so simple when you have the correct units :) for part b i did PV(5/3)=nRT to find V1 and then used boyle's law to find P2. I got...

    How can I calculate final pressures in a reversible argon expansion?

    isothermal and adiabatic please help! Homework Statement Hello, I have been stuck on this problem for about an hour so any hep would be greatly appreciated! One mole of argon at 25 degrees C and 1 atm pressure is allowed to expand reversibly t a volume of 50 L (a) isothermally (b)...
