All problems assume ideal gas $($IG$)$ behavior. $R=8\mathrm{.}3145Jmo{l}^{-1}{K}^{-1}=0\mathrm{.}082057Latmmo{l}^{-1}{K}^{-1}.$

Use J unit to report eneraies.

If the initial volume of the IG in Problem $1$ is $5\mathrm{.}00L,$ what is the minimum amount of

irreversible work needed to compress this IG with a constant pressure? What is that

pressure? What is the change of entropy of the system?
