A container of air (with a fixed volume of 1 ft^3)develops a slow leak. The container originally is at 900 degrees at 14.696 psi. 1/3 of the air leaks out and the process is adiabatic.
a) write conservation of mass for this process (list any assumptions)
b) write conservation of energy for this process (list any assumptions)
c) write the entropy equation for this process (list any assumptions)
d) solve for the final temperature, pressure, and the entropy production.
