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 2.50xx10^-2 N. m^-1?If an air bubble of the same dimension were formed at a depth of 40.0 cm inside a container containing the soap solution (of relative density 1.20), what would be the pressure inside the bubble? (1 standard atmosphere pressure is 1.01xx10^5 Pa.).

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 2.50xx10^-2 N. m^-1?If an air bubble of the same dimension were formed at a depth of 40.0 cm inside a container containing the soap solution (of relative density 1.20), what would be the pressure inside the bubble? (1 standard atmosphere pressure is 1.01xx10^5 Pa.).
Answer» Solution :Excess PRESSURE = 20.0 Pa (soap BUBBLE), 10.0 Pa (air bubble), TOTAL pressure `1.06xx10^5 Pa`
