Can anyone help me with chemistry?
1.Explain each of the following observations: A> Although they have ample supplies of oxygen gas, air passengers experience discomfort when the cabin pressure altitude undergoes a drop in air pressure B> New tennis balls are sold in containers under pressure. C> After declining from a high mountain, the reduced, half-filled plastic bottle from which you drank while you are at the summit now seems a little dented or crushed .>>>> This question comes to predicting GAS behavior: PRESSURE-VOLUME>> Help me plz
A) The pressure causes the lungs to compress and make it harder to intake air. B) If they were not so balls would eventually deflate over time because the differences in air pressure of air in the ball and in the air, the ball will gradually compress small amounts of air. C) Differences in air pressure within the plastic bottle vs air outside makes it compress.
