Edit
Are the following scenarios equivalent?1. a sealed enclosure placed in a vacuum chamber and the pressure decreased to 30000 ft. above sea level.2. the same sealed enclosure with air nozzle attached, valve opened until gauge reads 10psi (no vacuum cahmber involved)Also, what is the relationship of pressure and tenperature inside a sealed enclosure. Is PV=nRT applicable?I have an sealed industrial computer with a touch screen on the front. Once the unit has been in the field for some time, some units have "inflated" touch screens. Somehow pressure is building up enough to violate the seal of the touch screen and blow it up..
