Internal pressure of the smaller bubble is higher than the internal pressure of the larger bubble.

Vedclass · Answer

(A) The excess pressure $\Delta P$ inside a soap bubble is given by the formula $\Delta P = \frac{4T}{R}$,where $T$ is the surface tension and $R$ is the radius of the bubble.Since the surface tension $T$ is constant for both bubbles,the excess pressure is inversely proportional to the radius,i.e.,$\Delta P \propto \frac{1}{R}$.Therefore,a smaller radius $R$ results in a higher excess pressure $\Delta P$.Thus,the internal pressure of the smaller bubble is higher than the internal pressure of the larger bubble.

Two soap bubbles have different radii but their surface tension is the same. Mark the correct statement.

If a soap bubble expands, the pressure inside the bubble:

An air bubble of radius $1.0 \ mm$ is observed at a depth of $20 \ cm$ below the free surface of a liquid having surface tension $0.095 \ J/m^2$ and density $10^3 \ kg/m^3$. The difference between pressure inside the bubble and atmospheric pressure is . . . . . . $N/m^2$. (Take $g = 10 \ m/s^2$)

An air bubble doubles in radius when it rises from the bottom of the sea to the surface. If the atmospheric pressure is equal to the pressure exerted by a $10 \, m$ column of water,then the depth of the sea is $... \, m$. (Assume surface tension is negligible.)

If two soap bubbles of different radii are connected by a tube,
