Problem 2 (60 pt). One kmole ( N ) of argon gas at T_(1)=300K is initially confined to half
of an insulated and stationary rigid tank. The other half is evacuated. The volume (V) in
each half is 0.2m^(3). The partition between the two halves is removed, and the argon
expands to fill the entire tank. Assume that the constant volume heat capacity for argon
under ideal gas conditions is ((3)/(2))R.
(10 pt) What is the energy balance for this process?
(10 pt) What is the appropriate departure function to be used with the van der Waals
equation of state for this process?
(30 pt) Calculate the final gas temperature, T_(2)(K), assuming that argon is a real gas. Use
the van der Waals equation of state in your calculations. For argon, the van der Waals
constants are a=0.1355J(m^(3))/(m)ole^(2) and b=0.03201 liter/mole. Solve using an integral
from the attached list.

Problem 2 (60 pt). One kmole (N) of argon gas at T1 = 300 K is initially confined to half of an insulated and stationary rigid tank. The other half is evacuated. The volume (V) in each half is 0.2 m3. The partition between the two halves is removed, and the argon expands to fill the entire tank.
