An object is place inside a large cylinder (d=4m; h=30m). The object is sealed inside the cylinder with a movable disc floor that can be raised or lowered. When sealed, the air inside is at a gage pressure=700Pa and a temperature=20C. The object is initially at an elevation of 40m. Patm=101.3kPa a. (16 pts) How much air is in the cylinder with him when he is sealed? (kg) b. (16 pts) Assuming the cylinder has no leaks and rises slowly enough to maintain a constant temperature, what are the absolute (kPa) and gage pressures (Pa) inside when the disc raises to an elevation of 62 meters
