Why small air bubbles rises slowly through the liquid whereas the bigger one rises rapidly?

Explain,why an air bubble inside a transparent liquid behaves like a diverging lens.

Why does an air bubble in a jar of water shine brightly?

A small bubble rises from the bottom of a lake, where the temperature and pressure are 8^(@)C and 6.0 atm , to the water's surface, where the temperature is 25^(@)C and pressure is 1.0 atm . Calculate the final volume of the bubble if its initial volume was 2mL .

When an air bubble rises in water, what happens to its potential energy?

A transparent cube of side 210 mm contains a small air bubble. Its apparent distance, when viewed through one face of the cube is 100 mm and when viewed through the opposite face is 40 mm. What is the actual distance of the bubble from the second face and what is the refractive index of the material of the cube?

On being slowly passed through water, PH_3 forms bubbles but NH_3 dissolves. Why?

Derive an expression for the rise of liquid in a capillary tube and show that the height of the liquid column supported is inversely proportional to the radius of the tube.

A hollow sphere is filled with water through a small hole in it. It is hung by long thread and as water slowly flows out from the hole at the bottom, one finds that the periods of oscillation first increases and then decreases. Explain. Why.
