Sir,
Suppose a soap bubble contains a gas of density d1 and air outside it of density d2. Then will the expression for excess pressure inside the bubble be 4T/R where T is the surface tension of soap solution and R the radius of the bubble? If not, what will be the mathematical expression in that case?
