Directions for Balloons and Buoyancy Lab https ffphet colorado edulenlsimulationflegacyfballoons-and-buoyancy Balloons & Buoyancy 1. You are flying from Denverto Boston and you bring along a 1/2full bottle of shampoo that was well sealed before you left Denver You land in Boston and proceed to your hotel (a) The number of air molecules within the shampoo - ' borne (circle/highlight one): - a has decreased has stayed the same has increased (b) if the walls of the shampoo borne are strong and rigid so that the borne retains the same shape as itwas before you left. how does the pressure of the air inside the borne compare to the pressure of the air in Boulder and to the pressure of the air in Boston? The pressure of the air in the bottle is the pressure of the air in Boulder and the pressure of the air in Boston (select one pair) less than, less than less than, same as same as, less than same as, same as greaterthan, less than less than, greater same as, greatertnan greatertnan, same as greatertnan' greaterthan (c) The air pressure at sea level is 14.? lbsfin2 The air pressure in Boulder is 20% less then the air pressure at sea level How many lbs of force are being exerted on each square inch of the shampoo borne? (d) if your shampoo bottle is like most. and its walls are not very rigid. you notice that the walls have collapsed a bit (torthis problem, considerthe bottle to be like a plastic Ziploc) so not at all rigid) i When the shampoo bottle collapses, the volume of the shampoo bottle and the pressure of the air inside the bottle (select one pair) decreases, decreases decreases stays the same stays the same) decreases increases, decreases decreases increases stays the same) stays the same stays the same) increases increases) stays the same increases increases Explain the physics prinCIples and reasoning behind your answer. in the Simulation. keep temperature constant and try changing the volume Note the temperature of the gas will increase as you change the volume Waitforthe simulation to automatically return the temperature to its original value (removing it) and then evaluate how the pressure has changed and why ii. if the walls are acod as in the plastic Ziploc case. how will the pressure inside compare to the pressure outSIde the bottle when you are in Boston but have not yet opened the shampoo? (select one) The pressure inside will be lower The pressure outside Will be lower The pressure inside and outside will be the same Explain your reasoning behind your answer iii Assuming the temperature in Boston and Boulder are the same and using an original volume of 1J2 liter of air (1 L borne) What is the new volume of air in the bottle? iv if you now heat your shampoo bottle up, you can get itto expand backto its original volume. Explain why this works
