An air bubble originating from an under water diver has a radius of 5 mm at some depth h. when the bubble reaches the surface of the water, it has a radius of 6.6 mm. assuming the temperature of the air in the bubble remains constant, determine the absolute pressure at this depth h. the acceleration of gravity is 9.8 m/s 2 . answer in units of pa.

Absolute Pressure at depth h =

Explanation:

Given:

Assumptions:

According to Ideal Gas Law,

where,

For the given case, the temperature of the air bubble is constant. The number of molecules of the bubble also does not change, therefore,

PV = constant.

The pressure at the surface is equal to the atmospheric pressure,

The pressure at depth h is equal to sum of atmospheric pressure and the pressure of the water upto depth h,

Using these values,

The absolute temperature at that depth is given by

the components of a vector are the parts of the vectors that are to each other.
