Justify your answer

Answer 1

Given:

Bubbles rising from the bottom of the water-filled in a bottle are depicted in the picture attached.

Which is the correct figure?

Solution:

Figure c) shows the correct diagram.

• At higher depths , the pressure of a liquid column is higher as compared to the lower depths.

• Since the ambient pressure is higher at higher depths , the bubbles get compressed and have smaller radius.

• At lower depths , the ambient pressure is much lesser and the bubbles get de-compressed. This results in increasing of the radius of the bubbles.

• So, smaller bubbles at the bottom of the bottle and larger bubbles at the top of the bottle represents the correct figure.
