Write the equation of excess pressure (pressure difference) for the bubble in air annd bubble in water.

Derive an expression for excess of pressure (pressure difference) inside the drop and bubble.

Write importance of turgor pressure .

Bubble in air have …… free surface

Statement -1 : A large soap bubble expands while a small bubble shrink, when they are connecteed to each other by a capillary tube. Statement -2 : The excess pressure (due to surface tension) inside a spherical bubble increasesee, as its volume decreases.

The lower end of a capillary tube of diameter 2.00 mm is dipped 8.00 cm below the surface of water in a beaker . What is the pressure required in the tube in order to blow a hemispherical bubble at the end in water ? The surface tension of water at temperature of the experiments is 7.30xx10^(-2)Nm^(9-1) . 1 atmospheric pressure =1.01xx10^(5)Pa . Density of water =1000kg//m^(3),g=9.80ms^(-2) . Also calulate the excess pressure .

The lower end of a capallary tube of diameter 2.50 mm is dipped 8.00 cm below the surface of water in a beaker .What is the pressure required in the tube in order to blow a hemispherical bubble at the end in water ? The surface tension of water at temperature of the experiments is 7.30xx10^(-2)Nm^(-1) . 1 atmospheric pressure 1.01xx10^(5)Pa . Density of water =1000kg//m^(3),g=9.80ms^(-2) .Also calculate the excess pressure .

Write the formula of pressure at depth h in liquid .

The excess pressure inside one soap bubble is three times that inside a second soap bubble, then the ratio of their surface area is:
