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

A liquid of specific gravity 1.5 is observed to rise 3.0 cm in a capillary tube of diameter 0.50 mm and the liquid wets the surface of the tube. Calculate the excess pressure inside a spherical bubble of 1.0 cm diameter blown from the same liquid.

In the state of weightlessness, a capillary tube is dipped in water, then water

Assertion : The water rises higher in a capillary tube of small diameter than in the capillary tube of large diameter. Reason : Height through which liquid rises in a capillary tube is inversely proportional to the diameter of the capillary tube.

When a liquid rises inside a capillary tube , the weight of the liquid in the tube is supported
