Calculation OF S. E.||Excess pressure inside a drop||Excess pressure inside a bubble

Tow soap bubbles A and B are formed at the two open ends of a tube. The bubble A is smaller then bubble B. If the valve on the tube connecting the two bubbles is opened and air can flow freely between the bubbles, then

Suppose there is an air bubble of radius inside the air cavity of radius R inside a water drop of radius 3R as shown in figure. The ratio of gauge pressure at point C to gauge pressure at point B is: -B

Excess Pressure In Soap Bubble

The vapour pressures of two pure liquids A and B that form an ideal solution are 300 and 800 torr, respectively, at tempertature T . Calculate a. The composition of the first drop of the condensate. b.The total pressure when this drop is formed. c. The composition of the solution whose normal boiling point is T . d. The pressure when only the last bubble of vapour remains. e. Composition of the last bubble.

The vapour pressure of two pure liquids, A and B that form an ideal solution are 300 and 800 torr respectively, at temperature T. A mixture of the vapour of A and B for which the mole fraction of A is 0.25 is slowly compressed at temperature T, Calculate (a) the composition of the first drop of the condesate, (b) the total pressure when this drop is formed, (c) the composition of the solution whose normal boiling point is T, (d) the pressure when only the last bubble of vapour remains, and (e) the composition of the last bubble.

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 -
