An air bubble at the bottom of a lake 52.0 m deep has a volume of 1.50m^3. if the temperature at the bottom is 5.5 degree's celsius and at the top is 18.5 degree's celsius, what is the volume of the bubble just before it reaches the surface?

The volume of the bubble near the surface will be 9.47 m³

Explanation:

Given that,

Depth = 52.0 m

Volume = 1.50 m³

Temperature at bottom = 5.5°C

Temperature at the top = 18.5°C

We need to calculate the pressure at the depth 52.0 m

The pressure is

Where, = Pressure at the surface

= Pressure at the depth

Put the value into the formula

We need to calculate the volume of the bubble just before it reaches the surface

Using equation of ideal gas

Now, The equation of at bottom and top

Put the value into the formula

Hence, The volume of the bubble near the surface will be 9.47 m³

scientific laws are the result of testing theories and proving them to be facts.
