A rigid, insulated vessel is divided into two compartments connected by a valve. Initially, one compartment, occupying $1\mathrm{.}0f{t}^3,$ contains air at $50l\frac{b_f}{i}{n}^2$;$725R,$ and the other, occupying $2\mathrm{.}0f{t}^3,$ is evacuated. The valve is opened and the air is allowed to fill both volumes. Assume the air behaves as an ideal gas and that the final state is in equilibrium.

Determine the final temperature of the air, in $R,$ and the amount of entropy produced, in $Bt\frac{u}{}R.$

Step $1$

Your answer is correct.

Determine the final temperature of the air, in $R.$

$T_f=R$
