In Jager's method, at the time of bursting of the bubble
The internal pressure of the bubble is always greater than external pressure
The internal pressure of the bubble is always equal to external pressure
The internal pressure of the bubble is always less than external pressure
The internal pressure of the bubble is always slightly greater than external pressure
The excess pressure in a soap bubble is double that in other one. The ratio of their volume is .............
The surface tension of soap solution is $25 \times {10^{ - 3}}\,N{m^{ - 1}}$. The excess pressure inside a soap bubble of diameter $1 \,cm$ is ....... $Pa$
A soap bubble in vacuum has a radius of $3 \,cm$ and another soap bubble in vacuum has a radius of $4 \,cm$. If the two bubbles coalesce under isothermal condition, then the radius of the new bubble is ....... $cm$
The pressure at the bottom of a tank containing a liquid does not depend on
When an air bubble of radius $r$ rises from the bottom to the surface of a lake, its radius becomes $\frac{{5r}}{4}$.Taking the atmospheric pressure to be equal to $10\,m$ height of water column, the depth of the lake would approximately be ....... $m$ (ignore the surface tension and the effect of temperature)
