Problem 61PE

If the gauge pressure inside a rubber balloon with a 10.0-cm radius is 1.50 cm of water, what is the effective surface tension of the balloon?

Solution

Step 1 of 3

We need to find out the effective surface tension of the rubber balloon.

We know the equation for pressure inside the balloon is,

...............(1)

Where is the radius of the balloon

is the surface tension of the balloon.
