Ammonia vapor enters an adiabatic, steady-state throttling valve at T = 30C and P = 10 bar,

Question:

Ammonia vapor enters an adiabatic, steady-state throttling valve at T = 30°C and P = 10 bar, illustrated in Figure 6-1. If it leaves the throttling valve at P = 1 bar, what is the exiting temperature? Ammonia P = 10 bar T = 30C P = 1 bar T = ?
