hello, i am having some troubles with this problem. please take a look and help me if you can. an open-ended can 1ft long is originally full of air @ 70 F. the can is now immersed in water. assuming that the air stays at 70 F and behaves like an ideal gas,how high will the water rise in the can? the is immersed at 10 ft deep into water tank open to the atmosphere. thanks in advance. please show the work i tried to find the pressure of the water at the bottom of the tank. then i assume x to be the height of the water in the can with the air on top of it. considering the can as the system now, there is a relation between the compressed air in the can and the water inside the can. the pressure at the bottom of the can which is also equal the pressure at the bottom of the tank, will be the sum of that of the air plus dgX of the water (density* gravity* X) with X being the height iam looking for. i have this one realtionship and i can't think of another one to get the height X out of it... can anyone help?
