How Does Altitude Affect Atmospheric Air Volume and Diver Pressure?

AI Thread Summary
Altitude decreases atmospheric air volume due to lower air density at higher elevations. As a diver descends, pressure increases, with each 33 feet of water adding approximately one atmosphere of pressure. At a depth of 132 feet, a diver experiences around five atmospheres of pressure. The weight of a cubic foot of water is essential for calculating pressure, as it influences the pressure exerted on a diver. Understanding these principles is crucial for safe diving practices and accurate pressure calculations.

Does anyone know the equation for the second one, and any ideas about the first one?


*What affect does altitude have on atmospheric air volume?

* A diver goes down to a depth of 132 feet. How many atmospheres of pressure are on the diver?
 
Physics news on Phys.org
Find the weight of a cubic foot of water. One square inch on the bottom of that cubic foot represents 1/144 of the area on the bottom. The column of water above that square inch is 12 inches high and also represents 1/144 of the weight of the cubic foot of water. That mass (1/144 of the mass of 1 cubic foot of water) in pounds will be exerted on the square inch of space immediately below it. If you calculate the mass in pounds, you now have the pressure in pounds per square inch or PSI resulting from immersion in 1 foot of water.

It's up to you to do the rest.

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
