Consider filling the cylinder of compressed argon from a high-pressure supply line. Before filling. the cylinder contains 10 bar of argon at room temperature, 295 K. The valve is opened, exposing the tank to a 50 bar line at room temperature until the pressure of the cylinder reaches 50 bar. The valve is then closed. For argon, c = (5/2)R and the molecular weight is 40 g/mol. You may = 0 kJ/mol. use the ideal gas model. Assume that at T = Treference, Hreference a. b. What is the temperature right after the valve is closed? If the cylinder sits in storage for a long time, how much heat is transferred?

the cylinder contains 10 bar of argon at room temperature, 295 K. The valve is opened, exposing
the tank to a 50 bar line at room temperature until the pressure of the cylinder reaches 50 bar. The
valve is then closed. For argon, c = (5/2)R and the molecular weight is 40 g/mol. You may
= 0 kJ/mol.
use the ideal gas model. Assume that at T = Treference, Hreference
a.
b.
What is the temperature right after the valve is closed?
If the cylinder sits in storage for a long time, how much heat is transferred?
