Question

A scuba diver releases a balloon containing 173 L of helium attached to a tray of artifacts at an underwater archaeological site. When the balloon reachesthe surface, it has expanded to a volume of 361 L. The pressure at the surface is 1.00 atm; what is the pressure at the underwater site? Pressure increases by 1.0 atm for every 10 m of depth; at what depth was the diver working? Assume the temperature remains constant.

Pressure at underwater site = 2.08 atm

Depth of underwater site = ?????? I'm stuck on this part

Explanation / Answer

Pressure increased from 1.00 atm (surface) to 2.08 atm (at the underwater site) - a difference of 1.08 atm

1.08 atm increase * 10 metres depth = 10.8 metres depth

1 1.0 atm increase

So depth of underwater site = 10.8 metres
