Formation of bubble are in Column - $\mathrm{I}$ and pressure difference between them are given in Column - $\mathrm{II}$. Match them appropriately.

Column - $\mathrm{I}$	Column - $\mathrm{II}$
$(a)$ Liquid drop in air	$(i)$ $\frac{{4T}}{R}$
$(b)$ Bubble of liquid in air	$(ii)$ $\frac{{2T}}{R}$
	$(iii)$ $\frac{{2R}}{T}$

Two long parallel glass plates has water between them. Contact angle between glass and water is zero. If separation between the plates is $'d'$ ( $d$ is small). Surface tension of water is $'T'$ . Atmospheric pressure = $P_0$ . Then pressure inside water just below the air water interface is 

In capillary pressure below the curved surface of water will be

Write the equation of excess pressure (pressure difference) for the bubble in air and bubble in water.

A soap bubble of radius $3\, {cm}$ is formed inside the another soap bubble of radius $6\, {cm}$. The radius of an equivalent soap bubble which has the same excess pressure as inside the smaller bubble with respect to the atmospheric pressure is .......... ${cm}$ 

A spherical drop of water has radius $1\, mm$ If surface tension of water is $70 \times {10^{ - 3}}\,N/m$ difference of pressures between inside and out side of the spherical drop is ........ $N/{m^{ - 2}}$
