The compressibility factor provides a quick way to assess when the ideal gas law is valid. Use a solver

to find the minimum temperature where the fluid has a vapor phase compressibility factor greater

than $0\mathrm{.}95$ at $2$MPa. Report the value in $C,$ without units.

$($a$)$ oxygen

Be sure your answer corresponds to a vapor root. Liquid volumes will often be near $Vb$ and can

give $Z1$ at very low temperatures. Use a Z$-$factor chart to provide an initial guess.
