C The pressure outside the balloon went down and the pressure inside went down.
When a balloon is filled with oxygen gas, the gas particles inside the balloon exert pressure on the walls of the balloon, causing it to expand and become full. However, if the pressure outside the balloon decreases, such as when the balloon is taken to a higher altitude, the pressure inside the balloon will also decrease. This decrease in pressure can cause the balloon to shrink and appear half full.
Oxygen gas is used to fill a balloon and a short time later the balloon is observed to only be half full. Explain this observation.
