Let's assume that oxygen goes through an isobaric process in which its specific volume changes from $0\mathrm{.}1\frac{m^3}{k}g$ to $0\mathrm{.}5\frac{m^3}{k}g.$ Complete table below for Air assuming it is an ideal gas with $R=259\mathrm{.}8\frac{J}{k}g.$ K at constant pressures $P=0\mathrm{.}5$MPa,$0\mathrm{.}7$MPa,$1\mathrm{.}2$MPa. Then, plot these isobaric processes on a $T-v$ diagram.

Note: This problem shall be completed in Excel or a similar tool not by hand.
