A 3 ft^3 adiabatic rigid container is divided into two equal volumes by a thin membrane. Initially, one of these chambers is filled with air at 100 degrees Fahrenheit, and 100 psia, while the other chamber is evacuated. Determine the internal energy change of the air when the membrane is ruptured, also find the final pressure of the chamber.
