If a soap bubble expands, the pressure inside the bubble:
increases
remains the same
is equal to the atmospheric pressure
decreases
An air bubble of radius $0 .1\, cm$ is in a liquid having surface tension $0.06\, N/m$ and density $10^3\, kg/m^3$. The pressure inside the bubble is $1100\, Nm^{-2}$ greater than the atmospheric pressure. At ....... $m$ depth is the bubble below the surface of the liquid ? $(g\, = 9.8\, ms^{- 2})$
An air bubble in a water tank rises from the bottom to the top. Which of the following statements are true
In capillary pressure below the curved surface of water will be
Derive the formula for excess of pressure (pressure difference) inside the drop and bubble.
The excess of pressure inside a soap bubble is twice the excess pressure inside a second soap bubble. The volume of the first bubble is $n$ times the volume of the second where $n$ is
