1.	Surface tension is a property of liquid and it causes capillary rise in small tubes. Excess pressure inside a liquid drop is 60xxN/m^2. What will be the excess pressure inside a liquid bubble of the same radius formed by the same liquid?
Answer» SOLUTION :EXCESS pressure inside a drop = 2S/R = `60xxNm^-2` `THEREFORE` Excess pressure inside abuble = 4S/R = `120Nm^-2`
