A container with flexible sides is filled with $6$ lb of propane at $50$ psi. The initial container volume

is $3\mathrm{.}6$ ft$3$

$.$ The entire system is cooled at a constant pressure until its temperature reaches $0\backslash$deg F$.$

Draw this process on a T$-$v diagram and determine the energy transfer via work and heat transfer

and the change in energy stored in the system $($kJ$).$
