## Homework Statement

A vessel of internal volume 9 m^3 is lowered with its mouth downward into fresh water lake until the volume of the air in the vessel becomes 5 m^3. Given that the atmosphere pressure is 760 mmHg, what is the verrtical distance of the water level inside the vessel from the surface of the lake? Temperature remains unchanged. Density of water = 1000 kg/ m^3 of mercury = 13600 kg / m^3

## Homework Equations

## The Attempt at a Solution

I dont know how to approach this problem. Is it right that the pressure inside the vessel is the same as the atmosphere pressure? What formula should i base on to calculate the height of water ?[/B]
