A 20 ft3 container has two partitions. Partition A, whose volume is 11 ft3, contains six Ibm of air at 85 °F. Partition B, on the other part, is evacuated. The air expands freely to fill the entire container, and comes to rest with temperature of 90 °F. At this final state, a pressure gauge connected to the vessel reads 25 psi, and the atmospheric pressure is 14.7 psi. What was the initial pressure in kPa?
