I have some really basic questions regarding pressure. I hope they aren't too trivial. Here I go:
1) We know air pressure at a point develops because of the weight of all air present above that point. So when I stand beneath something, say a loft, now there's a very little air above me, so there should be a sharp fall in air pressure, but it doesn't happen. Why?
2) When we keep a container open in air, and then close it. We treat the pressure of air inside the container as equal to the atmospheric pressure. Why is that so?
Please help me as I have these really basic questions. Thanks! :)
