Consider a 35-l evacuated rigid bottle that is surrounded by the atmosphere at 105 kpa and 22°c. a valve at the neck of the bottle is now opened and the atmospheric air is allowed to flow into the bottle. the air trapped in the bottle eventually reaches thermal equilibrium with the atmosphere as a result of heat transfer through the wall of the bottle. the valve remains open during the process so that the trapped air also reaches mechanical equilibrium with the atmosphere. determine the net heat transfer through the wall of the bottle during this filling process. the gas constant of air is 0.287 kpa·m3/kg·k.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
