Pressure inside two soap bubbles is and atmosphere. What is the ratio between their volume?
Step 1. Determine the ratio between their radius.
Excess Pressure in the bubble one is
Similarly, excess pressure in the bubble two is
The excess pressure of the bubble one of radius with surface tension is given as,
The excess the pressure for the bubble two of radius with surface tension is given as,
Step 2. Determine the ratio between their volume.
The volume of soap bubble is calculated by where represents the radius of soap bubble.
Hence, the ratio between their volumes is
