It is given
that an open-closed pipe of length
As the air inside the pipe has been compressed to half of its initial value at constant temperature, the pressure inside it would have become double of its initial value, that is, 2.0 atm.

contains air at atmospheric pressure. It is thrust vertically into a
fresh water lake until the water rises halfway up in the pipe. We
have to find the depth h of the lower end of the pipe. We may assume
that the temperature is the same everywhere and does not change.
will therefore be 2.0 atm. At that the depth the pressure will be
