Two soap bubbles have different radii but their surface tension is the same. Mark the correct statement
Internal pressure of the smaller bubble is higher than the internal pressure of the larger bubble
Pressure of the larger bubble is higher than the smaller bubble
Both bubbles have the same internal pressure
None of the above
Excess pressure of one soap bubble is four times more than the other. Then the ratio of volume of first bubble to another one is
An air bubble of radius $r$ in water is at depth $h$ below the water surface at same instant. If $P$ is atmospheric pressure and $d$ and $T$ are the density and surface tension of water respectively. The pressure inside the bubble will be
A capillary tube of radius $r$ is dipped in a liquid of density $\rho$ and surface tension $S$. If the angle of contact is $\theta$, the pressure difference between the two surfaces in the beaker and the capillary
The pressure of air in a soap bubble of $0.7\,cm$ diameter is $8\, mm$ of water above the pressure outside. The surface tension of the soap solution is ........ $dyne/cm$
Two soap bubbles coalesce to form a single bubble. If $V$ is the subsequent change in volume of contained air and $S$ change in total surface area, $T$ is the surface tension and $P$ atmospheric pressure, then which of the following relation is correct?
