How would you use the photometer to find the effect of wind on the water uptake by the shoot?
If you are referring to a the rate of water uptake in plants, then a live plant stem is placed in one end of the uptake photometer which is filled with water by a reservoir and tap. at the other end of the photometer there is a scale with an air bubble. Over time, as the plant takes in water, the air bubble will move along the scale and this can be used to work out how much water the plant is using. dont know if this will be of any help :)

How does air pressure affect a substance's boiling point Relate this principle to boiling water at sea level and on a mile high mountaintop?
Im not extremely sure about this but i think it has to do with how tight the substance's molecules are because i think with lower air pressure the molecules are loose so they boil because they aren't tight. If you had water at sea level the molecules would be tighter so they would have a higher boiling temperature. But at higher places like a mountain top the have a lower boiling temperature because they are loose. Also, in space where there is no air pressure if you brought up a glass of water even though it is freezing up there it would boil immediately.

Why will iron rust faster in an open container than it will if placed in air tight container?
It is moisture and air that causes metal to rust, therefore if something is air tight and doesn't get much air it can't easily rust.
