Two soap bubbles A and B are kept in aclosed chamber where the air is maintained at pressure `8 N/m^(2)`. The radiiof bubbles A and B are 2cm and 4 cm , respectively. Surface tension of the soap-water used to make bubbles is 0.04 N/m. The ratio of `n_(B)//n_(A)`is ( where `n_(A)` and `n_(B)` are the numbe of moles of air in bubbles A and B,respectively.)

The work done in blowing a soap bubble of 10 cm radius is (Surface tension of the soap solution is 3/100 N/m)
The work done in blowing a soap bubble of 10 cm radius is (Surface tension of the soap solution is 3/100 N/m)
Two soap bubbles having radii 3 cm and 4 cm in vacuum, coalesce under isothermal conditions. The radius of the new bubble is
An isolated soap bubble is kept in a container in which the pressure is maintained at P_(0) . The bubble is given some charge due to which its radius increases to R_(0) . If the surface tension of the soap bubble is T, then the charge given to the bubble is
Two spherical soap bubbles of radii a and b in vacuum coalesce under isothermal conditions. The resulting bubble has a radius given by
The excess pressure inside a soap bubble is
Two soap bubbles A and B have radii r_(1) and r_(2) respectively. If r_(1) lt r_(2) than the excess pressure inside
