Question

The excess pressure inside an air bubble released in mercury is..........

Answer 1

Answer:

The excess pressure inside an air bubble released in mercury is

$P_{ex} = \frac{2S}{R}$

Explanation:

As we know that air bubble is inside mercury then excess pressure is the amount of pressure that exceeds the outer side pressure of the mercury.

So here we will have one free surface so

$P_{ex} = \frac{2S}{R}$

now here we have

S = surface tension of the mercury

R = radius of the air bubble
