Excess Pressure in Drop and soap Bubble|| Angle OF Contact|| Liquid Rise in Capillary Tube

A drop of water and a soap bubble have the same radii. Surface tension of soap solution is half of that of water. The ratio of excess pressure inside the drop and bubble is -

Excess of pressure inside a soap bubble is

Excess pressure inside a soap bubble of radius r and surface tension T is

A : Excess pressure inside a soap bubble is (4T)/r symbols have their usual meanings). R : The pressure difference across a curved surface of radius of curvature r is (2T)/r) . There are two surfaces in a soap bubble.

The excess pressure inside a soap bubble of volume V is P . Then excess pressure inside a soap bubble of volume 2V is
