A vessel filled with air under pressure ...

A vessel filled with air under pressure `p_(0)` contains a soap bubble of diameter d. The pressure having been reduced isothermally n fold, the bubble diameter increased `eta` fold. Calculate the surface tension of siap water solution.

Text Solution

Verified by Experts

The correct Answer is:
`(p_(0)d(1-eta^(3)/n))/(8(eta^(2)-1))`
