Question

same quantity of water and kerosene are taken in two identical beakers. from the bottom of the two beakers air bubbles are rising.
1.what is the reason for growth in size of the air bubble in both beakers as it rise upwards?
2.what is the reason for the large size of the air bubbles in kerosene compared to that in water? ​

Answer 1

The dynamics of an air bubble rising in a liquid has been an active area of research due to its relevance in many

natural and industrial applications (see for instance [1–4]). In dimensionless formulation, a rising bubble can be

completely described by four dimensionless numbers: the Galilei number
