What is the excess pressure inside a bubble of soap solution of radius

1.	What is the excess pressure inside a bubble of soap solution of radius 5.00 mm. given that the surface tension of soap solution at the temperature (20^@C) is 2.50 times 10^-2 N m^-1? If an air bubble of the same dimension were formed at depth of 40.0 cm inside a container the soap solution (of relative density 1.20] what would be the pressure inside the bubble?[1 atmospheric pressure is 1.01 times 10^5 Pa).
Answer» Solution :Excess pressure inside the soap BUBBLE =20.0 Pa excess pressure inside the AIR bubble in soap solution =10.0Pa OUTSIDE pressure for air bubble =`1.01 times 10^5+0.4 times 10^3 times 9.8 times 1.2=1.06 times 10^5 Pa`. The excess pressure is so small that up to THREE significant FIGURES, total pressures inside the air bubble is `1.06 times 10^5 Pa`
