Question

Explain why a gas bubble released at the bottom of a lake grows in size as it rises to the surface of lake.​

Answer 1

Answer:

Volume of a gas in bubble is inversely proportional to the pressure applied.

As the bubble rises from the bottom of the lake, the pressure surrounding the bubble drops hence the volume of the bubble increases.

P = P₀ + hρg,              

where h is the depth of the point of pressure from the surface of the water.

Answer 2

Answer:

A gas bubble released at the bottom of a lake grows in size as it rises to the surface of the lake because pressure decrease continuously when it go up in water. At any point under the surface of liquid, pressure is proportional to its depth.
