On a sunny day with no wind, a balloon is filled with helium and floats away into the sky. Eventually, the balloon pops. Three cases of an identical balloon. In case A, the net pressure above the balloon points down, and the net pressure below the balloon points upward with a larger magnitude. In case B, the net lateral pressure is represented by several horizontal arrows on each side of the balloon pointing toward the balloon. In case C, the external pressure is represented by several arrows surrounding the balloon pointing inward and perpedicular to the balloon's surface. The internal pressure is represented by several arrows of greater magnitude inside the balloon that point radially outward. Which case explains why the balloon pops at high elevation? Case A: The net pressure acting upward and downward on the balloon squeezes it until it bursts. Case B: The net lateral pressure squeezes the balloon until it bursts. Case C: The pressure inside the balloon is greater than the pressure outside the balloon, causing the balloon to expand until it bursts.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
