These Bubbles Are Magnetic

Two soap bubbles have radii in the ratio 2:3. Compare the excess of pressure inside these bubbles. Also compare the woeks done in blowing these bubbles.

Two air bubbles are formed in water (surface tension 0.72 N/m). The bubbles come together to form a bigger bubble. What will be radius and sense of curvature of common surface of that bubble? The radii of bubbles are 0.003 m and 0.005 m.

A and B are two soap bubbles. Bubble A is larger than B. If these are now joined by a tube then

The soap bubble formed at the end of the tube is blown very slowly. Draw the graph between excess of pressure inside the bubble with time.

Two air bubbles with radius r are present in water. Are these bubbles attracted or repelled?

Coloujrs of thin soap bubbles are due to

Two soap bubbles are blown. In first soap bubble excess pressure is 4 times of the second soap bubble. The ratio of the radii of the first and second soap bubble is

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

The execc pressure inside the first soap bubble is three times that inside the second bubble. Then the ratio of the volumes of the first and second bubbles is
