In an evacuated enclosure, a verticalcylindrical tank of diameter D is sealed bya 3.00 kg circular disk that can move up anddown without friction. Beneath the disk is aquantity of ideal gas at temperature T in thecylinder. Initially the disk is atrest at a distance of h = 4.00 m above the bottomof the tank. When a lead brick of mass9.00 kg is gently placed on the disk, the diskmoves downward. If the temperature of the gasis kept constant and no gas escapes from thetank, what distance above the bottom of the tank is the disk when itagain comes to rest?
