Answer:

<u></u>

  • <u>The diameter of the bubble would be about 400mm</u>

Explanation:

This problem is solved using Boyle's law because you assume a fixed amount (number of moles) of air and that the temperature remains constant:

       PV=constant\\\\P_1V_1=P_2V_2

Where:

  • P₁ = 1.6 atm
  • V₁ = 5,000 liters
  • P₂ = 155 atm
  • V₂ = unknown

Substitute and solve for V₂:

       V_2=\dfrac{1.6atm\times 5,000liters}{155atm}\\\\\\V_2=52liters

Since the number 5,000 has one significant figure, you must round your answer to one significant figure. That is 50 liters.

Now, you must calcualte the diameter of the bubble, assuming the shape is a sphere:

Remember that 50 liters = 50dm³.

     Volume=\dfrac{4}{3}\pi\ (radius)^3

    50dm^3=\dfrac{4}{3}\pi (radius)^3\\\\radius = 2dm

The diameter is twice the diameter = 4 dm = 40cm = 400mm
