In a continuous manufacturing process, chlorodifluoromethane (chclf2), initially at 10 bar and 420 k, passes through an adiabatic pressure-reducing valve so that its pressure drops to 0.1 bar (this last pressure low enough that chclf2 can be considered to be an ideal gas). at these operating conditions, the gas can be represented by a one-term virial equation of state: pv / rt = 1 + b / vb=297.6-256100/tandcp=27.93+0.093t what is the temperature of the chlorodifluoromethane exiting the valve?
