a gas cylinder is filled with argon from a gas line that contains $50$ bar of argon at room temperature $(21$ degrees C$).$ the cylinder is filled with argon until the pressure and temperature of the cylinder reaches $50$ bar and $432\mathrm{.}5$ K$,$ respectively. The value of the cylinder is then closed, and the cylinder is left in storage for a very long time. you may assume that argon behaves as an ideal gas and has a cp$=(5/2)$R$.$ if the cylinder sits long enough at room temperature to reach equilibrium, $(1)$ what would be its pressure and $(2)$ how much heat will be transferred from the cylinder and to the surroundings? note: MW argon $=39\mathrm{.}948$ g$/$mol $($d$)$ how much heat is transferred from the tank? $($e$)$ what is the final pressure of the tank?
